15 Best Maternity Halloween Costumes in 2026

Updated for 2026 — This article has been reviewed and updated with the latest recommendations.

Growing a human is hard work, and if your due date lands anywhere near October, you deserve a Halloween costume that celebrates the bump rather than trying to hide it. The best maternity costumes lean into the belly, turning it into the centerpiece of a creative look that gets laughs, compliments, or both.

These fifteen costume ideas work whether you are crafting something yourself or buying a ready-made outfit.

Each one has been chosen because it actually fits a pregnant body comfortably and does not require standing for hours in something restrictive.

1. Juno (Paulie Bleeker Couples Costume)

All you need is a striped shirt, a hoodie tied around the waist, and your natural bump. If your partner dresses as Paulie Bleeker in running shorts and a headband, you have an instantly recognizable couples costume that costs almost nothing and stays comfortable all night.

• Difficulty: Very easy
• Comfort level: Maximum (just regular clothes)
• Cost: $0 to $15 (items you probably own)
• Best for: Couples costumes, casual Halloween events

2.

Magic 8 Ball

A black dress or shirt with a circular white panel on the belly reading a Magic 8 Ball answer like "Signs Point to Yes" or "Ask Again Later." This is one of the most popular maternity costumes because it is simple, clever, and the belly is literally the focal point.

• Difficulty: Easy (iron-on transfer or painted fabric)
• Cost: $10 to $20
• Best for: Office parties, trick-or-treating

3.

Avocado

A green dress or tunic with a brown circle on the belly representing the pit. Your bump becomes the avocado seed. This costume works especially well if your partner wears a matching avocado half without the pit, making you the complete avocado together.

• Difficulty: Easy
• Cost: $15 to $25
• Best for: Couples or solo wear

4. Basketball Player

Grab an oversized basketball jersey, tuck it above the bump, and let the belly do the work.

Add a headband, wristbands, and high-top sneakers for the full effect. The beauty of this one is that basketball jerseys are already loose and breathable, so you stay comfortable.

• Difficulty: Very easy
• Cost: $20 to $30 (jersey plus accessories)
• Best for: Sports fans, casual events

5. Goldfish in a Bag

Wear an orange shirt under a clear poncho or large clear bag cinched at the top with a ribbon. Your bump covered in orange becomes the goldfish, and the clear layer represents the water bag. Add blue cellophane or tissue paper for water effect.

• Difficulty: Moderate (requires clear bag or poncho)
• Cost: $10 to $15
• Best for: Creative costume contests

6.

Skeleton with Baby Skeleton

The maternity skeleton shirt has become a classic for good reason. Black shirt with a white skeleton print on the torso and a tiny baby skeleton on the belly. Plenty of online retailers sell these pre-made in maternity sizes.

• Difficulty: None (buy pre-made)
• Cost: $15 to $25 for the shirt
• Best for: Easy, universally recognized

7.

Kool-Aid Man

A red outfit with the Kool-Aid face printed on the belly. When someone asks about it, crash through an imaginary wall and yell the catchphrase. The round belly sells this costume better than any store-bought version ever could.

• Difficulty: Easy (printed iron-on transfer)
• Cost: $10 to $20
• Best for: People who commit to the character

8.

Mummy

Wrap white fabric strips or medical gauze loosely around a white base outfit, leaving the belly prominently wrapped. This is comfortable because you control how tight or loose the wrapping is, and it looks great in photos. Add some dark eye makeup for the full effect.

• Difficulty: Moderate (wrapping takes time)
• Cost: $10 to $15
• Best for: Classic Halloween look

9.

Bun in the Oven

Attach a printed oven door image to the front of your shirt with the belly positioned behind the oven window, with a bread roll or bun visible inside. Literally a bun in the oven. It is the most dad-joke maternity costume possible, and that is exactly why people love it.

• Difficulty: Easy
• Cost: $5 to $15
• Best for: People who love puns

10.

Winnie the Pooh

Red crop top (or regular shirt pulled up) exposing the belly, yellow pants or leggings, and bear ears. Pooh's signature look is a too-small red shirt over a round belly, which means pregnancy finally makes this costume 100% screen-accurate.

• Difficulty: Easy
• Cost: $15 to $25
• Best for: Disney fans, cute and comfortable

Buying Guide: Maternity Costume Tips

Prioritize comfort over everything. You are carrying extra weight and your center of gravity has shifted. Avoid costumes that require heels, restrict movement, or have tight waistbands. Stretch fabrics and loose fits are your friends.

Layer for temperature control. Pregnancy runs hot. If you are trick-or-treating outdoors, wear layers you can remove. A costume that works with a tank top underneath is better than one that requires a specific undershirt.

Account for growth. If you are buying a costume weeks before Halloween, remember your bump may be noticeably bigger by October 31. Size up or choose designs that stretch and accommodate growth.

Skip face paint if you are sensitive. Pregnancy can make skin more reactive. If you have not used face paint recently, patch test it first. Many theatrical makeups contain fragrances and chemicals that irritated skin may react to differently during pregnancy.
