Best Nursing and Pumping Bras

Quick Summary

The best nursing bra is the Kindred Bravely Simply Sublime Nursing Bra, according to four testers from the What to Expect staff and a poll of more than 9,900 What to Expect community parents who voted in our 2023 Mom Must-Have Awards. When choosing a nursing or pumping bra, medical professionals and moms say the most important factors to consider are comfort, fit and nursing-friendly features like clip-down straps.

Best Nursing Bras

If you’re considering breastfeeding, it’s a good idea to invest in a nursing bra or two. But there are so many options, and it’s hard to know which ones will be best for you. (I know from experienced — I nursed both of my sons.)

To compile this list of the best nursing bras, I started out by speaking to International Board Certified Lactation Consultant Amy Peterson about what to look for in a nursing bra. Above all else, she recommends choosing a nursing bra that is comfortable; most women do well with a cotton and spandex blend, which is breathable and stretchy. 

Next, I considered my personal experience nursing my two sons and testing out many nursing bras over the course of those two years. I also spoke to three moms on the What to Expect staff who nursed themselves; in total, those women nursed six children. We have experience with all of the bras that made it onto this list of the best nursing bras.  

Finally, I combed through the results from the 2023 What to Expect Mom Must-have Awards, which surveyed more than 9,900 mothers in the What to Expect community about their favorite products across 31 categories, including nursing bras. 

Ultimately, the best nursing bra for you is one that fits most comfortably and makes it easiest for you to access your breasts. You may have to try a few to find the best one for you — and you may even find that you need a different bra for different scenarios. But any of the options that made this list of the best nursing bras will be a good place to start.

Many moms who breastfeed will also pump at some point. You could get a separate pumping bra for your pumping sessions, of course, but the genius of Kindred Bravely’s two-in-one combo is that you don’t have to.

As the winner in the 2023 What to Expect Mom Must-Have Awards for Best Nursing Bra, the Kindred Bravely Sublime Hands-Free Pumping and Nursing Bra has two layers of fabric: One that pulls down to reveal horizontal slits that hold pump flanges in place, and a second that exposes the whole breast for direct feeding. 

“The Kindred Bravely was easy to use, super comfy and had good padding, although it could be a bit bulky under a shirt,” says Lisafe Carreon, What to Expect’s Senior Product Manager. She added that, overtime, the bra didn’t hold flanges as tightly. “I had to keep readjusting the strap so that the flange didn’t lose suction.”

Like the brand’s Simply Sublime style, which is strictly for nursing, this combo bra is made from a soft, stretchy nylon/spandex blend. It has wireless construction that many moms say provides plenty of support. It’s also available in a dozen sizes so you can find the perfect fit.

In fact, one of the biggest pros of Kindred Bravely is the way the brand does their sizing: the bra comes in sizes S-XXL and S-XXL Busty, so if you’re someone with large breasts (which probably only increased in size during pregnancy and breastfeeding!) you can get a bra made with larger boobs in mind.

One final pro for the Sublime Hands-Free Pumping & Nursing Bra: It’s compatible with most breast pumps on the market, with WTE community members saying it accommodates the SpectraMedela and Haakaa pumps with ease. Wearable pumps, which often feel best worn with a clip-down nursing bra, also work with this hands-free style. If you’re going to invest in just one nursing bra and plan to pump at any point, this is the one to get.

Community Reviews
  • “Love the Kindred Bravely nursing/pumping bras! They are supportive yet comfortable.”

  • “The Kindred Bravely nursing and pumping bra is super supportive because of the two layers. I don’t like the pumping bra part but I still wear it constantly because of the support it gives me.”

  • “I just bought two nursing/pumping bras from Kindred Bravely and they are LIFE CHANGING. So cozy and soft and sooo much support, while still looking nice under blouses and shirts. They have double latches that allow you to pump or nurse all from the same bra. Little pricey but absolutely worth it especially if going back to work!”

If you like bras with a bit of padding but don’t enjoy dealing with those removable pads (why are they so hard to stuff back in after washing?!), this Auden bra is the answer. Here’s why: The cups are molded so the padding is incorporated. Thanks to this clever design, the bra keeps its shape in the wash and gives you a little lift and shape as well.

What to Expect moms love the Auden bra’s price point (at just $17, it’s one of the most affordable styles we’ve seen), but also appreciate the supportive fit and soft, seamless fabric. Moms in our community say they were able to wear Auden bras regularly throughout their nursing journeys, and the fabric held up well over time.

“I’ve always been small chested, and didn’t really know how to deal with my larger postpartum boobs. Auden’s nursing bra was one of the few that gave me the lift and support I needed to feel comfortable with these new breasts,” say Leah Rocketto, What to Expect’s Associate Commerce Director, who went from a 32A to 32C. She adds that Auden’s nursing bra was comfortable enough to wear to bed — something she unintentionally did many times — though she mostly wore the brands’ sleep bra to bed. 

Leah also liked that the bra had a hook on the back to create racerback straps, so she was able to wear it with a variety of tops. This also offers more support, as many moms in the community note. Although it’s not as supportive as a sports bra, this feature also makes it a good choice for lighter workouts such as yoga.

Community Reviews
  • “I also wore the Auden ones with my first, nursed him for 18 months and my ducts never clogged.”

  • “I had really great luck with the Auden seamless nursing bras from Target. They were my go-tos with my first baby.”

Technically not a bra, Bravado’s cleverly designed piece of fabric that looks like the cups on a nursing bra without straps. You attach it onto the clips of an existing nursing bra, open the cups and use your pump through the figure-eight openings. They hold flanges securely so you can use it hands-free.

Reviewers from the What to Expect community rave about how comfortable and convenient this product is. Working moms especially appreciate that they can bring the attachment to the office and use it whenever they need to pump without changing their bra.

Because this product attaches onto nursing clips on an existing bra, it needs to be used with a clip-down style — so just keep in mind that you won’t be able to use it to turn a regular bra into a pumping-friendly bra. But if you already have a number of clip-down nursing bras and don’t want to invest in a dedicated pumping bra, this is the perfect workaround.

Community Reviews
  • “If you’re pumping [Bravado! Designs has] a pumping bra attachment that is amazing because it clips onto any nursing bra (no need to hold the flanges or change bras).”

  • “I hated the regular pumping bras I found but really like my nursing bras. I finally found this one that clips onto my nursing bra. The fit is kind of weird where the nipple holes are but it works for pumping and I feel like it holds my pump in place better.”

Although it’s not technically a nursing bra, Calvin Klein bras are a favorite among nursing moms — myself included. I invested in countless nursing-specific styles when I started breastfeeding my firstborn. But as the months went on, I found myself reaching for my Calvin Klein bralettes again and again.

With soft, breathable fabric, a snug elastane band and comfortable fit, these bras are incredibly comfortable. The entire bra is soft and feels like a hug — I love that there are no tight straps or plastic pieces whatsoever to dig into your skin. The fabric isn’t overly tight and the scoop neckline is low, so I always found it easy to move the fabric aside to nurse or pump. 

Calvin Klein bralettes are relatively affordable (and you can often find them on sale), but they’re highly durable, too. In fact, I was able to wear the same styles I bought after my first son was born two years later while nursing my second.

Note that this is not the most supportive bra on our list — the elastane band does provide some light support, but it’s definitely not ideal for the early postpartum days when you’re heavily engorged or for anyone who needs a lot of support (for context, I was a 32C while nursing). The fabric is also on the thinner side, so you’ll need to wear nursing pads if you tend to leak in between nursing sessions. (In my experience, the fit accommodates nursing pads well as long as they have sticky adhesive.) Once my nursing supply was established and I was leaking less, these bras were my absolute favorite, especially for lounging around the house and as a sleep bra.

Few sports bras get as much love in the What to Expect community as SheFit, a brand that offers a number of innovative features that help their bras stand out from the pack. Like most sports bras, the SheFit Ultimate Sports Bra has full coverage and support for high-impact workouts. But it also has clever straps with adjustable hooks that let you change the straps from an “X” to an “H” back, plus a wide adjustable band to help you find the perfect fit around your ribs. Best of all, though, is the front zipper, which makes these bras nursing-friendly and also prevents chafing.

Moms in the What to Expect community love how adjustable SheFit bras are, and note that since you can change the fit so easily, they’re a solid option for breastfeeding moms who need support during high-impact workouts. SheFit also has an excellent size range, from XS to 6X.

Just be mindful to avoid bras that have a very constricting fit. As with underwire, too-tight styles can increase your risk of developing mastitis. For that reason, your best bet may be to size up to make sure the fit isn’t overly tight.

Community Reviews
  • Shefit has an amazing adjustable one. It’s not cheap but so worth the money.

  • “Shefit! It's super adjustable and has a front zipper. It'll also hold [you] so that it is not uncomfortable while [you’re] moving. Plus it'll work for after nursing since it's not maternity/nursing. Highly highly recommend.”

  • “They’re really pricey, but I love my SheFit sports bras. Adjustable straps and under-bust, front clasp and front zipper, and high-impact support even with my E cup+ boobs.”

If you have larger breasts and have been struggling to find a well-fitting nursing bra, moms in the What to Expect community overwhelmingly recommend Bravado! Designs nursing bras. The brand’s Body Silk Seamless Nursing Bra is one of their most popular styles and a top What to Expect community pick.

This is a wireless nursing bra, but reviewers say it still offers very good support. The molded cups provide ample coverage and the fabric is stretchy enough to accommodate changes in your cup size.

“I’d still be wearing it [the Bravado! seamless silk nursing bra] if it hadn't worn out,” says staffer Joyce Slaton. “The material was exceptionally soft and smooth and didn't pill in the wash. It's light support, so I wouldn't wear it running, but around the house or to go out for errands, it was so comfortable and easy to wear.”

One thing to keep in mind is that some reviewers say these bras can run a little smaller than standard. So if you’re not able to try on this style in person, you might consider sizing up. 

Community Reviews
  • “36DDD — my favorite is the Bravado Designs Body Silk Seamless nursing bra. I bought a second one when my LO was a week old because I couldn’t live without it when it was in the laundry. I found their size chart to be very accurate too.”

  • “I’m larger chested too and I LOVE the Bravado Designs full cup nursing bra. You can get it on Amazon with prime shipping or from their website. Also if you’re pumping they have a pumping bra attachment that is amazing because it clips on to any nursing bra (no need to hold the flanges or change bras).”

  • “I’ve been searching high and low for a good nursing bra. I’m smaller framed but bigger chested and I always struggle finding bras, swimsuits, etc that are comfortable and provide good coverage. So I just wanted to share that I found THE ONE! It’s the Bravado Designs Body Silk Seamless Nursing Bra.”

When it comes to materials, few bra brands can compete with Bodily. With its lightweight, stretchy and buttery-soft fabric — a viscose/micromodal/elastane blend that’s OEKO-TEX certified, meaning the materials have been tested for potentially harmful substances — Bodily’s The Everything Bra is next-level comfortable. I wore this nursing bra regularly after the birth of my second baby, and can confirm that the fabric is gloriously breathable and truly feels cloud-like when you slip it on. 

This bra is also very well-designed for nursing. The clip-down straps are easy to undo with one hand, but you can also pull down the elastic neckline. The front straps adjust for changes in cup size, and the five-row back closure helps accommodate band size changes. It’s a particularly good bra for the newborn period — in fact, it was developed with a lactation consultant to ensure it supported optimal breast health in the first few months of breastfeeding, during which time you’re more likely to develop clogged ducts.

But while this bra is well-suited for smaller or medium-sized breasts, a number of reviewers with larger breasts say it doesn’t offer adequate support. If you have larger breasts or are looking for extra support or lift, this may not be the best nursing bra for you.

Community Reviews
  • “I am in love with the ones from Bodily. They are so soft and yet somehow still supportive. They look good and function well as a regular bra in the meantime.”

  • “1000% the Bodily Everything Bra, it’s heaven. I’m pretty small though. It might not be practical for the more bodacious babes but it is insanely comfy and made with breast/nipple health in mind.”

At $54, the Soma Enbliss costs about the same as our pick for the best nursing bra — but unlike the Kindred Bravely model, the Soma bra can't double as a pumping bra. But if you don’t mind spending a bit more, moms in the What to Expect community strongly recommend investing in this option.

What makes these bras worth the splurge? Moms say the smooth, brushed fabric is invisible under T-shirts, has a flattering fit and feels buttery soft. With a low neckline, seamless construction and supportive wireless band, this is a perfect everyday bra that’s seriously comfortable — many reviewers say they look forward to wearing it. Moms in our community also say that this bra holds its shape well over time, even when worn and washed regularly.

Another bonus is the bra’s “real” look and feel, which some moms prefer over styles that clearly look like they’re designed for nursing. Still, this is definitely an excellent nursing bra, with features like adjustable straps and clip-down cups.

The Soma Enbliss scores points for its flattering fit and excellent support, but note that it may actually be too supportive and structured for those early newborn days when you’re more likely to be engorged and still getting the hang of nursing. During that time, a slightly looser bra may be a better fit.

Community Reviews
  • “I also have some from Soma (Enbliss Wireless Nursing Bra) that are great and more of a real bra feel.”

Plus-size moms in the What to Expect community say Gratlin nursing bras are some of the most supportive they’ve found. With cups up to 48E and adjustable straps that are thicker than many other nursing bras on the market, these bras are well-designed for larger breasts. The cups are non-padded and wire-free, but still very supportive, reviewers say.

The fabric, which is 90 percent cotton, is breathable and feels soft and comfortable against sensitive skin. A number of moms in our community also say these bras have held up well after frequent use, which is especially impressive given the affordable price. And while not as essential as fit and comfort, many moms also appreciate that this bra just looks like a “regular” bra. 

Although Gratlin bras have a lot of fans, a few reviewers dislike the shape of the cups, which have a horizontal seam that some say can show through certain shirts.

Community Reviews
  • “I know it's really hard to find plus-size nursing bras. … A good plus-size nursing bra up to size E is Gratlin Plus Size Cotton Maternity Nursing Bra.”

  • “I have two of the Gratlin cotton bras … they are still going strong after two years.”

  • “I know the struggle of finding a good reliable bra. Pre-pregnancy I was a size 34DDD and once I hit 9 weeks my boobs grew to a size 34G. I’ve always had the issues with finding a bra to keep the girls in and I always had spillage and support issues, but this bra is amazing! It feels and looks like a normal bra, no Grandma look to it. I’d say it has good support, my boobs have gotten a little bigger since I bought it and they are still staying in place. Definitely check it out.”

The pregnancy, breastfeeding and post-breastfeeding period are something of a rollercoaster ride for your breasts, which can go from bigger to biggest to smaller-than-they-started in the span of a few months. That can be a lot to adjust to, but even trickier if you find yourself frequently having to buy new bras to accommodate each new stage and size.

It’s not officially a nursing style, but Neiwai bras have a number of passionate fans in the What to Expect community, who rave about the brand’s flexible-fit design and ultra-stretchy fabric. Multiple What to Expect moms call these bras the most comfortable they’ve ever worn, and they particularly love Neiwai’s Cloudfit fabric, a nylon blend that’s incredibly silky, soft and luxurious-feeling.

This set combines Neiwai’s popular wireless bra with the matching brief, which makes it a great value (not to mention a nice way to try out the brand’s underwear, too).

Great for the ever-changing size of boobs during/after pregnancy and also stretchy enough for nursing but never loses its shape. My girlfriends and I have all stocked up after trying them.”

Wearable breast pumps such as the Elvie or Willow are intended to be used hands-free, but the key to being able to use them in this way is the right bra. While you can technically slip them inside any bra — it doesn’t necessarily need to be a nursing style — some moms find that many aren’t supportive enough to keep hands-free pumps securely in place.

Bodily’s The Do Anything Bra is a great solution: It’s not specifically designed to be a hands-free pumping bra, but What to Expect moms say it works very well for that purpose, thanks to its adjustable sliders and supportive fabric. (To accommodate a hands-free pump, reviewers recommend adjusting the straps for a slightly looser fit.) And with the front clips for breastfeeding access and openings for flanges, it’s also an excellent nursing bra and regular pumping bra to use with electric pumps such as the Spectra. That’s important, because true to its name, you can invest in one bra and use it for all three scenarios. 

As with Bodily’s other bras, the fabric is OEKO-TEX certified, a nice bonus. What to Expect moms rave about how soft and silky the fabric is, too. 

Compared to some other bras on this list, some reviewers say that it’s not the most supportive, so it may not be the best choice for those with larger breasts.

Size range: S-3X

Material: OEKO-TEX certified 76 percent polyamide, 24 percent elastane

  • “Bodily Do Anything! Super soft and silky, I've used my Elvie [pumps] in them and not had any issues.”

How to Find the Best Nursing Bra for You

Here are three factors to consider, according to International Board Certified Lactation Consultant Amy Peterson:

  • Comfort: The most important feature in a nursing or pumping bra is that it feels good when you wear it. So, this list prioritizes bras made of materials that support breasts comfortably and are gentle on skin, such as cotton (which is highly breathable) and spandex (which can stretch to accommodate fluctuating breast size).
  • Needs: Some moms exclusively nurse, while others exclusively pump. And then there are those who do both. It's impirtant to give some thought into how you'd like to feed your baby, as that may dictate the type of nursing bra you need. For this reason, we included a variety of nursing bras, pumping bras and combo bras 
  • Nursing-friendly features: Clip-down cups, highly absorbent pads or openings that allow for easy pumping access are a few features that can help make your nursing experience a little easier.

FAQs

For most people, nursing bras are the easiest way to breastfeed or pump — you just unclip and pull out a boob, which can be challenging to do if you’re wearing a regular bra.

“For most moms, nursing bras provide great comfort,” says Peterson. “When milk supply increases, your breasts become heavy. It can be uncomfortable to not harness them,” she explains. Nursing bras are specifically designed to do just that: provide extra support when you need it most.

The best nursing bras also prevent leaking. “Sometimes just walking around and having the weight of the breasts moving with gravity can cause a let-down reflex,” explains Peterson. If you use nursing pads, a nursing bra also holds those in place, helping to absorb leaks even more effectively.

“There are two pretty accurate windows for buying nursing bras,” says Peterson. “The first is when you're about 7½ to 8½ months pregnant. At that time, your body's carrying a lot of excess fluids. … That's a pretty good ballpark measurement of how big your breasts will be [when your milk comes in].”

The second window is six to eight weeks after your baby is born and your milk supply starts regulating. “By six weeks or so, your milk supply starts regulating,” says Peterson. “Everything gets a little softer, more like pre-pregnancy. But they're still larger than they were before you got pregnant.”

Once you’ve selected a brand and got your size and priorities down, you’ll probably want to invest in three or four bras, so you can keep up with laundry (also hard with a newborn).

The best way to determine the size of your nursing bra is to get fitted in person by someone at a maternity store who understands lactating breasts. But if you can’t get away (being at home with a newborn makes that hard!) or prefer to order online, Peterson recommends using the sizing chart provided by the brand you’re looking at, rather than a general size chart.

“General instructions are good, but sometimes the brand will have suggestions that are gonna make their bras fit better for you,” Peterson says. 

Throughout your breastfeeding journey, nursing or pumping bras should be well-fitting and offer the support you need without being too tight.

It’s important to avoidr styles that are too tight or constricting when you’re nursing, according to La Leche League International. That’s because underwire or other firm pieces can lead to clogged milk ducts or mastitis, a painful breast infection.

If you absolutely love underwire, your best bet is to choose a wireless stye in the early months of nursing, at which time you’re more likely to develop plugged ducts as your milk supply stabilizes. 

There are a few types of nursing bras. Here are the main ones to know about:

  • Clip-down bras: These nursing bras have cups that you can unclip when it’s time to feed, giving baby easy access and skin-to-skin contact. It’s a good idea to pick one that you can clip and unclip one-handed so you can hold your little one while doing it. Clip-down bras come in all styles and designs: with or without underwire, seamless, sports bras — you name it.
  • Dedicated pumping bras: These bras are meant to make your pump hands-free by holding it in place against your body. This is done by inserting the flanges into slits in the fabric around your nipple. Dedicated pumping bras are usually not meant to be used for nursing.
  • Nursing-and-pumping bras: These are all-in-one bras that combine the magic of nursing and pumping bras in one style. In addition to clip-down cups, these bras also have inserts to attach your pump flanges to your nipples. These are game-changers for moms who both nurse and pump, since you can wear one bra all day without needing to change.
  • Sleep bras: Because your breasts are so heavy when you’re breastfeeding, you may want to sleep with a nursing bra on, too. “A lot of moms will choose to have a sleeping bra to provide support and to hold those nursing pads into place,” says Peterson. Nursing sleep bras usually have a V-neck, criss-cross style so you can easily slide a boob out at night. They’re not usually meant to provide enough support to wear all day.
