How we chose the best pregnant Halloween costumes
The best maternity Halloween costume should be comfortable, fit well on your pregnant body and are easy to take on and off (because you may to have to pee a lot).
Sure, pirates’ and witches’ costumes will always be popular — and we’ve included some of those below — but some of the best Halloween costumes for pregnant women will also spotlight your belly so your bump can get in on the joke. Here are the features that we (and other What to Expect parents) prioritize in finding the right pregnant Halloween costume:
- Comfort: Your skin is extra-sensitive during pregnancy, so you’ll want to look for maternity costumes made out of soft, stretchy materials (like Spandex and cotton) to avoid irritation. It's also a good idea to look for costumes that are easy to take on and off for frequent bathroom breaks. (Think: T-shirts, loose dresses or one-pieces with snaps or zippers.)And it tends to be chilly in most places on Halloween, so opt for a costume that is inherently warm or naturally allows you to layer up with leggings and long sleeves underneath.
- Size ranges: If you’re buying ahead of the holiday, you’ll want to make sure you pick something that fits the size your bump likely will be in late October. Look for maternity-specific sizing (ideally with a wide range to accommodate your changing shape), or size up on a loose-fitting regular option. Super big, one-size-fits-most costumes can work well for pregnancy, too.
- Cost: If you’re not super into Halloween in general (or don’t think you’d get another year’s use out of a maternity costume), don’t feel like you have to splurge on an outfit. Lots of the options on this list are themed T-shirts that require just a few bucks and a little inventive flair — all you need to make a great costume in our book.

Best Disney Costume

Lots of WTE moms say that they have been (or want to be) Pooh for Halloween because it’s both cute and easy to accommodate your bump with minimal effort. This yellow maternity shirt when paired with a red crop top will transform you into Pooh at the blink of an eye — just add ears and a pair of trusty maternity jeans or leggings to complete the look. It’s great as a solo costume or as part of an ensemble with the rest of the crew from the Hundred Acre Woods. Plus, parents say the shirt is soft, comfortable and fits well no matter what trimester you’re in.
Sizes: S to XXL
Best Mummy Costume
Halloween Women Mummy Maternity Shirt
A little spooky, a little cute and totally comfy, this costume checks all the boxes. The mummy outfit comes as a cute stretchy top (much easier than a onesie jumpsuit for getting dressed or going to the bathroom!), and has a little baby mummy printed across your bump. Everything you could possibly want for a Halloween costume while you’re pregnant. Just note that some moms found the fabric a bit cheap and wrinkle prone — but for one night, most found that worth it!
Sizes: M to XXL
Best 'Star Wars' Costume
Crazy Dog Death Star T-Shirt
When your crew is going with a Star Wars theme, and you’re not sure how to fit in, you can’t go wrong with this “That’s no moon!” T-shirt. Your bump will make the Death Star look quite intimidating. Plus, if you’re a big Star Wars fan, you can wear it throughout your pregnancy — not just on Halloween. It comes in a range of colors, from navy to pink to gray.
Sizes: S to 3XL
Best Low-Effort Costume
Ice Ice Baby Maternity T-Shirt
One of the best things about being pregnant? You have a built-in excuse for just about everything, including not bothering with an entire Halloween costume if you don’t want to. Let this comfy tee do all the dressing up for you, which is perfectly punny with the creative “Ice Ice Baby” theme.
Sizes: S to XL
Best Pumpkin Costume
Spadehill Women Halloween Pumpkin Short Sleeve Shirt
Nothing says Halloween like a pumpkin. And with this comfy T-shirt, your bump will look like the perfect little jack-o’-lantern. Wear it with jeans for an understated look, or dress it up for trick-or-treating with a pair of black leggings and a green stem hat. FYI: It does run a little long, which some moms didn’t love. And order a size up if you’d like a slightly looser fit.
Sizes: S to XXL
Best Barbie-Inspired Costume
Pregnant Midge Costume
A pop culturally-relevant costume that’s ideal for pregnancy? Say no more! Bring Barbie’s pregnant friend Midge to life by pairing this purple floral maternity dress with comfy sandals and a long red wig.

Plus, the dress is cute enough to wear on its own.
Sizes: S to XXL
Best Space-Themed Costume
Spaceship Maternity Costume
Apparently UFOs are (probably) real, so what better way to pay homage to the little green men than dressing up as the “mother” ship? This cute minidress is designed to look like a flying saucer — with a panel over your bump that looks like an alien peeking out of a porthole. All you need are black maternity leggings and shoes and you’re good to go. Bonus points if you get your partner to dress up as an astronaut for a full group costume.
Sizes: S to XL
Best Kardashian-Inspired Costume
Kourtney Kardashian Pregnancy Announcement Costume
The eldest Kardashian sister made headlines this summer when she announced her pregnancy with Travis Barker by recreating a Blink-182 music video at one of the band’s shows — a clever way to break the news! Turn it into a pop culture-forward costume with a tight black bodysuit, short black wig, black maternity leggings, and a hand-made sign that says “______ I’m Pregnant.” Snaps at the crotch of bodysuit make bathroom breaks a cinch.
Sizes: S to XL
Best Horror Costume
"Rosemary's Baby" Costume
If you’re a fan of horror movies, there’s no better pregnancy Halloween costume for you than to dress as Mia Farrow in Rosemary’s Baby. All you’ll need are a blue bathrobe or housecoat (this fleece one is soft and warm, perfect for chilly Halloween evenings), a nightgown and a blonde pixie cut wig.
Sizes: S to XXL

Best Maternity Halloween Dress
Party City Adult Pumpkin Maternity Costume
Rare is the pumpkin costume that’s actually flattering — but we have to admit, this dress pulls it off! This form-fitting midi dress, complete with a jack-o’-lantern print over your baby bump, even has a glittery shine to it. The included green stem headband is a nice touch, too. The only downside is the limited size range.
