22 Halloween Costume for Pregnant Women (Must Try!)

When my cousin Priya was seven months pregnant, she showed up to a Halloween party in a store-bought “sexy witch” costume with a zipper that lasted about eleven minutes.

She spent the rest of the night wrapped in her husband’s flannel, eating cheese cubes, and telling everyone she’d be back in a real costume next year.

I have never forgotten how uncomfortable that looked.

Here’s what I learned from watching her: the best Halloween costume for pregnant women isn’t the most elaborate one.

It’s the one that fits your bump without squeezing it, lets you sit and pee without a wardrobe malfunction, and doesn’t make you overheat by 8 p.m.

The good news is that a growing belly is actually a fantastic costume prop, and plenty of ideas use it on purpose.

Below are 22 Halloween costume ideas for pregnant women, ranging from five-minute DIY looks to full group costumes.

I’ve flagged the easiest ones, the cheapest ones, and the ones that need a little planning ahead.

Prices are rough ballparks and they change, so check current listings before you buy.

And since Halloween is only a few weeks away, several of these can still be pulled together this weekend.

Quick Comfort Rules Before You Pick a Costume

Pregnancy changes what “comfortable” means, so a few ground rules save a lot of regret. Choose breathable fabrics, avoid anything tight around the waist, ribs, or chest, and plan for swelling by wearing flat, supportive shoes. Think about bathroom access too, because a jumpsuit with forty buttons is a bad plan at any trimester.

If you’re planning to use body paint, face makeup, or wear a heavy prosthetic, it’s worth asking your doctor or midwife what they recommend for your situation. Everyone’s pregnancy is different, and I’m a blogger, not a medical professional.

Costume Type	Effort	Approx. Cost	Best For
Bump-as-the-prop (pumpkin, bowling ball)	Low	$15–$50	Any trimester, easy DIY
Oversized sweater or dress look	Very low	$0–$40	Last-minute plans, hot flashes
Full character costume	Medium	$40–$120	Parties and photo shoots
Group or couples costume	Medium to high	$60–$200	Announcements and family photos

1. The Classic Pumpkin

It’s the most popular pregnant Halloween costume for a reason. An orange top or dress in a stretchy fabric, a green beanie or headband stem, and you’re done. The bump becomes the pumpkin, and everybody gets the joke instantly.

For a little more polish, add black felt or fabric shapes to make a jack-o’-lantern face across the belly. Use fabric adhesive tape or safety pins on the inside of the shirt rather than glue on your skin.

Pro tip: Pick an orange that leans warm and slightly muted. Bright neon orange looks cheap on camera, and it clashes with almost everything.

2. Bowling Ball

Wear a black fitted maternity dress or shirt, and add three small finger-hole circles at the top of your bump with black or gray felt. Add bowling shoes, if you have a pair, and you have a clever, comfortable costume that costs almost nothing.

It gets even better as a couple’s idea: your partner can wear a white outfit with red stripes as the pin, or a shirt that says “strike.” Both of you stay comfortable, and you’ll get plenty of laughs.

3. Disco Ball

This one is a showstopper for shiny lovers. A silver sequined dress or a stretchy silver top with small mirrored decals across the belly turns you into a walking disco ball, and it photographs beautifully under party lights.

Sequins can be scratchy, so choose a soft-lined fabric or wear a smooth layer underneath. A simple silver headband or small mirror-tile earrings finish it off.

4. Crystal Ball Fortune Teller

Here the bump is your crystal ball. A flowy patterned skirt, a jewel-toned scarf, gold hoops, and a scarf tied around your head give you the fortune teller look, and the belly becomes the prediction.

A friend of mine added a small sign that read “Ask me about the future,” pointing at her bump, and it turned into her party’s favorite conversation starter. Loose layers make this one very forgiving through all three trimesters.

5. Planet Earth (or Any Planet)

A blue or green maternity top with continents cut from felt makes a very cute Earth costume. For a different look, use orange and red swirls for Jupiter or add a paper-plate ring for Saturn.

Use fabric tape instead of glue so the pieces can be removed and reused. If you’re feeling ambitious, a light-up star headband adds a bit of magic.

6. Bun in the Oven

This is the pun that keeps on giving. Wear an apron, chef’s hat, and oven mitts, and attach a printed “oven” door to your belly, or simply add a sign that says “bun in the oven.” It’s quick, funny, and comfortable.

Cardboard works as a base, but soft craft foam is lighter and doesn’t dig in. Add a little “temperature dial” made from a paper plate and a brad for a satisfying finishing touch.

7. Watermelon

A green striped top with a pink or red belly circle creates a watermelon in seconds. Dot the belly with black seed shapes made from felt, and you have a costume that’s bright, summery, and surprisingly stylish for October.

It works especially well if you’re due in summer, but even in the fall it’s a fun, unexpected pick. A green headband with a little leaf adds polish.

8. Basketball Player (or Any Sport)

The bump makes a fantastic ball. Wear an orange top with black lines drawn or sewn across the belly, plus sneakers, sweatbands, and a jersey. If you prefer, switch it up with a soccer ball, baseball, or football.

This is one of the most comfortable options because athletic wear is stretchy and breathable. It’s also easy to build a matching partner costume, with your partner as the coach or referee.

9. Spooky Snow Globe

Pair a clear or translucent bump prop with tiny pumpkins, bats, or little ghosts inside, and you have a spooky snow globe. Use a clear plastic dome or a piece of stiff, clear vinyl fastened to the front of a dark dress.

It takes a bit more crafting than most ideas here, so start early. Keep the dome lightweight and secure it with soft straps so it doesn’t put pressure on your belly.

10. Witch With a Bubbling Cauldron

A black maxi dress, a pointed hat, and a bump covered in a green “potion” fabric make a witch costume that celebrates your belly. Add a paper or foam cauldron rim around your midsection, and let green tulle “bubble” over the top.

The maxi dress is doing the heavy lifting here, since it’s one of the most comfortable silhouettes in pregnancy. Add a tall hat and a broom, and you’re set.

Pro tip: Choose a black dress with a stretch waistline that sits above the bump, not across it. Waistbands that cut across the belly get uncomfortable fast.

11. Kangaroo With a Joey

Tan or brown clothes, kangaroo ears on a headband, and a soft “pouch” pinned across the belly turn you into a mama kangaroo. A little stuffed joey peeking out from the pouch completes the picture.

It’s cute, cozy, and easy to sew or pin together. It also works well with a partner or toddler in a matching animal costume.

12. Alien Abduction

Go for a sci-fi look with a silver jumpsuit, a headband with antennae, and a sign that says “I was abducted.” For extra effect, add a small toy UFO to your belly.

The hidden bonus is that space costumes are usually loose and stretchy. If you’re feeling silly, get a partner to wear a “farmer” outfit and hold a rope, and you have a couple’s costume with a story.

13. Cupcake

A pastel dress with a swirl of frosting made from fluffy tulle or batting around your chest and a cherry headband becomes a sweet cupcake costume. The belly turns into the cake, and the frosting sits on top.

Choose lightweight fabrics rather than stiff netting, which itches and traps heat. A sprinkle of felt “sprinkles” on the dress adds color without weight.

14. Mama Shark

Wear a gray or blue outfit with a fin on the back and a mouth shape around your belly. Add a matching baby shark headband for your toddler, and you have a family costume that’s bright and instantly recognizable.

This one is especially useful if you already have a small kid at home. Everybody dresses in the same color family, and nobody has to wear anything complicated.

15. Bride of Frankenstein

The tall white-streaked hair is the iconic part. A long, flowy white dress with stitched details, a wig with two white stripes, and pale makeup make for a glam-spooky look that’s comfortable and dramatic.

It’s a great pick for later pregnancy because the silhouette is loose, and you can choose flats or soft boots. You can also make a partner costume by having them dress as the monster.

16. The Sanderson Sisters (For Groups)

If you’re pregnant and want to join a group costume, this trio is a favorite. Pick the character with the flowiest dress, and let the others handle the bigger wigs and props. A long, empire-waist gown suits a bump beautifully.

Bring your own sitting cushion, because group parties can mean a long night on your feet. Friends are usually happy to carry the props for you.

17. Cozy Black Cat in an Oversized Sweater

When you feel too tired to do anything, this is the costume. Wear a black oversized sweater dress or a sweater with black leggings, add cat ears and a drawn-on nose and whiskers, and you’re a cat.

It takes about four minutes and stays comfortable for hours. Add a tail made from a black sock or a stuffed stocking, pinned lightly to the back.

18. Vampire in a Flowing Cape

A black maxi dress, a dramatic red-lined cape, and some deep-red lipstick create a gothic look that flatters a bump. A cape covers the belly if you prefer, or you can leave it open to show it off.

Capes are great because they don’t touch the waist at all. Choose a soft, drapey fabric so it moves well and doesn’t feel heavy on your shoulders.

19. Ladybug

A red top with black dots and a black headband with antennae make a sweet ladybug. Your belly is the round body, which is exactly the right shape for the costume.

Felt dots can be pinned or taped on. It’s also an easy costume to match with a toddler or a partner dressed as a garden gnome.

20. Garden Fairy or Flower Mama

Layered pastel or floral fabrics, a crown of fresh or faux flowers, and a little glitter turn you into a woodland fairy. It’s soft, romantic, and very forgiving on the belly.

Skip anything with a corset-style bodice. Choose an empire waist or a wrap dress instead, so nothing presses on the bump.

21. Hatching Dinosaur Egg

Here’s where I’ll go big: this is my favorite on the whole list. Wear a speckled cream or green top, add a cracked-egg shape around your belly with a small stuffed baby dinosaur peeking out, and you have a costume that’s adorable, funny, and completely unexpected.

The crack design can be made from felt, and the baby dinosaur can be a plush toy attached with a strap. It’s also a perfect reveal or announcement photo prop.

22. Classic Ghost

If you truly can’t be bothered, a white maternity dress or oversized white shirt with a drawn-on face works as a cute ghost. Add a sheer white shawl or a veil, and you’re covered.

It’s cheap, quick, and unbelievably comfortable. You can also add glow-in-the-dark details for a spooky touch, or wear a black-and-white striped scarf for a slight twist.

Pro tip: Keep a spare cardigan or jacket handy. Halloween evenings often get chilly, and a costume that doesn’t work with layers can end the night early.

Wrap-Up: What I’d Do If I Were Choosing This Year

If I were pregnant this Halloween, I’d pick something that uses the bump and asks very little of me. The pumpkin, the bowling ball, or the hatching egg would be at the top of my list, since they’re comfortable and get instant reactions. A good Halloween costume for pregnant women should make you feel like yourself, just with a fun twist.

Whatever you choose, prioritize comfort over cleverness. A costume you can wear for three hours beats a brilliant one you take off after twenty minutes. Set out your outfit the night before, keep snacks in your bag, and enjoy the excuse to celebrate this stage.

Soft, stretchy, breathable fabrics like cotton blends, jersey, and light knits work best. Avoid stiff, tight, or scratchy materials, especially around the waist and chest.

Can I wear costume makeup or body paint while pregnant?

Many people do, but it’s worth asking your doctor or midwife about anything you’re unsure of, especially for body paint or products with strong ingredients. Test any product on a small patch of skin first.

How do I stay comfortable in a costume for a long party?

Wear supportive flat shoes, choose breathable layers, and bring a snack and water bottle. Take breaks to sit down, and skip anything that restricts breathing or movement.

Are there good couples costumes for pregnant women?

Yes. Popular pairs include bowling ball and pin, alien and farmer, Frankenstein’s monster and bride, and mama kangaroo with a partner as a zookeeper.

Can I still use a costume from last year?

Often, yes, with tweaks. Swap tight waistbands for stretchy ones, use a maternity band, or turn a fitted dress into a cape or oversized layer to make room.

How do I make a costume announcement for my pregnancy?

Choose a costume with a bump-focused twist, like the bun in the oven or hatching egg, and take photos in good light. Add a small sign with your due date if you’d like.
