20 Pregnant Halloween Costumes That Make the Bump Part of the Fun
Need a Halloween costume that works with your bump? These cute, funny, creative, and easy ideas make dressing up feel fun, comfortable, and totally you.
Halloween hits differently when you’re pregnant.
Suddenly, the costume you saved months ago doesn’t sound quite as appealing, and squeezing into something uncomfortable for the sake of a joke definitely isn’t the plan.
Luckily, your bump opens up a whole new category of costume ideas. From a tiny skeleton to Barbie, a pumpkin, or a clever costume that has nothing to do with pregnancy at all, these are the ideas worth saving before October rolls around.
Pregnant Halloween Costumes
1. Bun in the Oven
There are pregnancy Halloween costumes that make you think, That’s clever, and then there are the ones everyone understands before you even say hello. Bun in the oven belongs firmly in the second category.
If you want a costume that requires almost zero explaining, save this one. It’s especially good for a casual gathering where you don’t feel like showing up in a full character costume.
2. Pregnant Barbie
Pregnancy does not mean you have to retire your love of pink, and Barbie is an easy excuse to lean into it. A pink dress, sunglasses, heels or flats, and a few Barbie-inspired accessories can give you the look without requiring an exact replica of a movie costume.
I’d skip anything too literal and make it feel like your version of Barbie. A little pink box, baby accessory, or Mama Barbie detail is all you need to get the idea across.
3. Skeleton With a Tiny Skeleton
If Halloween isn’t Halloween to you without something spooky, this is probably more your speed than the pumpkin costumes. Start with a black dress or black maternity set and let the skeleton design do the talking.
The tiny baby skeleton on the bump is what makes it work. You can go full skeleton makeup or keep the face completely natural and let the belly detail be the focal point.
4. A Pregnant Witch
Here’s my unpopular opinion: you don’t need to turn every pregnancy costume into a pun.
A black maternity dress, pointed hat, boots, and dramatic makeup can make a genuinely good witch costume all on its own. If you want the pregnancy to be part of it, give the costume a small Mama Witch detail, but honestly, I’d be just as happy leaving it at the witch.
5. Winnie-the-Pooh
If your growing bump already has you thinking about round, ridiculously cute costumes, Winnie-the-Pooh is an easy one to love. A yellow maternity dress or yellow top with a red shirt gives you the character right away, while a pair of bear ears finishes the look without requiring much more.
And honestly, the bump works in your favor here. You can lean into Pooh’s signature shape instead of trying to hide your pregnancy.
6. Mrs. Incredible
If you want a family costume, this is an easy winner. A red outfit, black mask, and Incredibles logo give you the character immediately, while your partner and kids can join as the rest of the family.
But even if you’re going solo, Mrs. Incredible works. There is something particularly funny about choosing an actual superhero costume while you’re already doing the very real superhero task of growing a human.
7. Pregnant Thor
This one is for the mom who wants her Halloween costume to have a little more attitude. Grab a black maternity dress or fitted top, add a red cape, Thor’s hammer, and a little superhero styling, and suddenly you’re Thor with a very important side quest.
8. Juno
If you don’t want a costume that screams pregnancy costume, borrow the look of Juno instead. A striped top, denim, sneakers, and a few recognizable details make the reference feel like an outfit rather than a costume.
And that’s exactly why I like it. You could wear the individual pieces again after Halloween, which is a much better deal than buying something that will live in the back of your closet forever.
9. Mother Nature
Not every Halloween costume needs a punchline. A flowing green dress, floral details, leafy accessories, or a flower crown can turn into a beautiful Mother Nature costume, and your pregnancy gives the idea a surprisingly fitting meaning.
You’re carrying new life while dressing as the personification of nature. If you’re taking maternity photos around Halloween, I’d put this one near the top of the list.
10. Cat and Yarn
If you want something cute with a little personality, turn your bump into the ultimate ball of yarn. Wear a black cat outfit with ears and whiskers, then wrap a long strand of chunky yarn around your outfit so it leads toward a little yarn ball positioned over your belly.
And if you already have cat ears at home, this could be one of those costumes you pull together without buying an entirely new outfit.
11. Cowgirl
Maybe you don’t want to dress as a pumpkin. Maybe you don’t want a baby skeleton on your belly. Maybe you just want to wear a great Halloween outfit.
Do that.
A denim shirt, comfortable jeans, boots, a cowboy hat, and a little Western jewelry can make a fantastic costume while letting you feel like yourself. Honestly, this is the category I’d look at first if you’re already tired of every costume suggestion involving your bump.
12. Thing 1 Costume
A red shirt, the Thing 1 logo, and you’re basically done. If you’re pregnant, the bump makes the costume even cuter, especially if you’re planning to add Thing 2 later.
You could keep it simple with leggings and sneakers, or go all in with the blue wig and a little Cat in the Hat styling.
13. Snowman
A white dress, black buttons, scarf, hat, and carrot-inspired makeup turn your bump into the middle of a snowman.
If you’re expecting a winter baby, though, this one becomes especially cute. It feels less like a random Halloween costume and more like a little snapshot of the season you’re in.
14. Pregnant Bee Costume
A black maternity dress or a black-and-yellow striped top gives you the bee look without much effort. Add little wings, antennae, and yellow shoes, and you’re ready to go.
If you want to make it pregnancy-specific, add a tiny bee detail near your bump or have your partner dress as a beekeeper.
15. Fortune Teller
A flowing dress, scarf, layered jewelry, and tarot cards make the fortune-teller costume easy to recognize. Then comes the obvious prediction: I see a baby in your future.
If you enjoy costumes where the joke unfolds as people look at the details, this is a fun one. You can make the whole thing feel theatrical with dramatic makeup and jewelry, or keep it simple and let the sign do the work.
16. Mummy
A mummy costume doesn’t need to mean wrapping yourself from head to toe in layers of fabric. Start with a loose white dress and add fabric strips strategically so your belly still has plenty of room.
This is one of those costumes where a little imperfect DIY actually makes it better. Don’t worry about making every strip symmetrical, you’re supposed to look like you’ve just crawled out of a tomb.
17. Mama Bird
A blue or brown outfit with feather details and a tiny bird motif gives you a sweet mama-bird costume without going full cartoon. Your bump naturally becomes part of the story.
I’d save this one for a maternity photoshoot or a family Halloween gathering. It has more of a storybook feel than a party-costume feel, which can be exactly what you’re looking for.
18. Pregnant Cruella
If you like a costume with a little attitude, Cruella is a fun excuse to go all in on the black-and-white look. A black maternity dress, faux-fur coat, red lipstick, and a half-black, half-white wig will do most of the work.
The pregnancy part can stay completely separate from the costume, which I actually prefer here. You get to dress up as a character you love rather than turning your bump into a prop, and the finished look can be surprisingly chic for a Halloween party.
19. Prego Pregnancy Costume
For a costume that gets the joke immediately, go as a jar of Prego. A red outfit with the Prego logo and a little pasta-inspired detail is all you really need to sell it.
The pregnancy pun is what makes this one fun: you’re literally Prego.
20. Pregnant Cow Costume
A cow costume is already cute, but pregnancy gives you an easy reason to lean into it. Start with a black-and-white outfit, add cow ears, a little makeup, and you’re set.
If your partner wants to join, a farmer costume is the obvious pairing, and probably one of the easiest couples’ costumes to pull together.
