Halloween is a fun opportunity to lean into creativity: and when you’re pregnant, your bump becomes the perfect accessory. Rather than hiding your belly, why not embrace it with a costume that highlights your growing baby? In this post, we’ll share five pregnancy-friendly ideas that are comfortable, clever, and crowd-pleasing. Use these as inspiration or adapt them to your style.

Before we jump into ideas, here are a few tips to keep in mind when choosing or creating your costume:

• Comfort & flexibility: You’ll want something that breathes, allows movement, and accommodates changes in your belly size.
• Easy bathroom access: Costumes that are easy to zip or pull off (or with openings) are ideal.
• Highlight the bump: The most fun costumes integrate the bump instead of hiding it.
• Simple DIY or easy buy: Materials you already have (felt, fabric paint, oversized shirts) go a long way.
• Couples or solo friendly: Some costumes lend themselves well to pairing with a partner, others stand alone.

With those in mind, here are the top five picks we love for 2025.

This is a modern classic for pregnant Halloween costumes. The idea is to wear a green tunic or shirt that fits loosely over your bump, then add a brown circle or “pit” design over your belly. Some costume retailers carry maternity avocado costumes to make it easier for you.

If you enjoy puns, this one is a classic. Turn your belly into a “bun in the oven.” You can create a DIY cardboard “oven” box or opt for a premade bun-in-the-oven costume.

This one is playful and colorful. Use a white shirt or dress as the base, then glue or sew on small, bright pom-poms or felt circles to represent gumballs around your bump. Some versions also include a red border or dispenser theme.

If you’re looking for a funny and simple maternity costume idea, go as a “Prego” pasta sauce jar because, well, you’re prego! This clever play on words always gets a laugh and is easy to pull together. All you need is a red dress or shirt, a “Prego” logo printed out (or drawn on cardboard), and a gold or yellow lid-style hat to top it off.

If you want a nostalgic, movie-inspired costume, Juno (from the film Juno) is a fun choice. Wear a striped shirt or tunic over your belly and pair it with a jacket or hoodie. Your partner can dress as Paulie. This costume lets you embrace your pregnant look rather than hide it.

• Start early: Give yourself time to make alterations or additions as your bump changes.
• Use stretch or jersey fabrics: These offer give and breathability.
• Avoid bulky or restrictive props: The simpler, the better for comfort.
• Test wear: Try on the whole costume a few days ahead to check mobility, bathroom access, and comfort.
• Mind temperature: Layer wisely so you can cool down if needed.

Halloween while pregnant doesn’t mean sacrificing style or fun. With a thoughtful costume that highlights your bump, you can celebrate in comfort and creativity. Whether you go punny, elegant, or nostalgic, any of these top five ideas or their variations can help you shine.
