It may be the most ghoulish time of year, but finding a Halloween costume during your pregnancy doesn’t have to be a frightening experience. Though the Halloween season is a time when kids can dress up as their favorite show character, superhero, or Disney princess — you and your bump can get in on the action too!

Whether you are in your first trimester or your third, don’t be afraid to show off your pregnancy bump this Halloween season. There are lots of fun, creative ways to embrace your growing belly with a head-turning maternity costume.

If you’re looking to match your significant other with a funny couples costume, or are wanting to find an outfit with a theme that works for the entire family, we've got you covered.

From easy T-shirt costumes and onesies (that are super comfortable) to last-minute DIY costume creations that will surely impress your friends and family, we’ve rounded up our favorite pregnancy Halloween costumes.

Bun Maker & Bun in The Oven Costume Set

Laugh alongside your friends and family as you and your beau poke fun at the age-old “bun in the oven” expression. This couples costume will provide the perfect LOL moment at any Halloween party or event. Plus, for those mamas in their first trimester, this costume is a fun way to reveal to others that you are expecting.

The pullover costume makes it super comfortable to wear for long periods of time and is also a great outfit choice for any weather. If it’s cold, simply throw on a pair of leggings and a sweatshirt underneath the costume. If it's hot out, wear it with a T-shirt and biker shorts. We love a versatile costume.

Winnie the Pooh Dress

This adorable Winnie the Pooh costume is sweeter than, well, honey. The maternity yellow and red bodycon dress will emphasize your curves and really highlight your baby bump. The dress is made with a breathable material that will be super comfortable throughout the day, and you can complete the look with a set of ears.

You definitely can’t go wrong with this maternity costume. Plus, the red shirt and yellow dress can be worn separately, meaning that post-Halloween you can sport this look. We love a multi-use costume that can be worn throughout your pregnancy.

Maternity Skeleton

Are you ready to announce your pregnancy? This maternity skeleton T-shirt is a simple Halloween costume to showcase your exciting baby news. If you’re searching for an inexpensive, last-minute costume to unveil your little pumpkin, this maternity skeleton baby tee is a great option.

A little bit ghoulish combined with a whole lot of comfort, this graphic tee is a fun way to get into the Halloween spirit and unveil your pregnancy news to friends, family, and even coworkers.

Jack Skellington Pregnancy Shirt

Is The Nightmare Before Christmas one of your all-time favorite Halloween movies, too? Do you watch the Disney film on repeat during the month of October? If Jack Skellington is one of your favorite movie characters, you must snag this T-shirt with the Pumpkin King’s face. Seriously, we love a good T-shirt costume.

Basketball Maternity Costume

Score a few points this Halloween with this basketball-inspired costume. If you’re a sports enthusiast, or your partner is, the two of you will totally be cheering after wearing this adorable handmade costume. Let’s face it, sporting a creative T-shirt is a total win.

This costume comes complete with a net to wear around your baby bump for a 3D effect. However, you can also order the shirt without the net. Either way, this maternity costume is a slam dunk. (Sorry, we had to say it. Also prepare to hear a lot of these types of corny jokes when you wear it to a party.)

If you are looking to make this a couples costume, your partner can dress up as a referee. If you already are the proud mom of one (or two) little ones, get your gang to dress up as basketball players.

‘Barbie’ Movie Midge Doll Wig

Unsurprisingly, we will probably see a few Barbie-inspired Halloween costumes this year. After the release of Greta Gerwig’s highly successful film starring Margot Robbie as the iconic blonde Mattel doll, we expect to see loads of pink outfits hit our Instagram and TikTok feeds in October.

But one costume that can make you stand out among the sea of Barbies is to dress up as her best friend, Midge. In the 2023 film, fans meet the pregnant doll in Barbieland.

While your baby bump is not detachable (like the Midge’s), show off your growing pregnancy body and your obsession with the Barbie movie by dressing up like Midge. To do this, you simply need to rock a long red-haired wig, and your favorite floral dress.

If you and your non-pregnant besties are looking for inspiration for a group costume for a Halloween party, dressing as different Barbie dolls is the perfect option. Plus, your significant others can dress as Ken dolls. Cue the viral dance moment!

Pumpkin Face Costume

Dressing up for a work event can seem like a daunting task, and coordinating a work-friendly costume while pregnant can make it even harder.

This simple jack-o-lantern shirt is great to wear in and outside of the office no matter your profession. The plain black shirt with the orange pumpkin face will totally show off your baby bump this fall season.

Thor Avengers: Endgame Hammer

Forget the bulging muscles, “Bro Thor” in Avengers: Endgame is totally our favorite Avenger! This funny DIY costume worn by Siobhán Alvarez Borland will for sure have you embracing (and showing off) your baby bump.

Sport your favorite pair of cozy fleece pajamas or sweatpants, a blue T-shirt, and a pair of sunglasses. To complete the look, wield Thor’s iconic hammer and you’re all set. This easy costume is great for Marvel movie fans.

‘Cast Away’ Wilson Ball Costume

“Wilson!”

Though Tom Hanks has starred in a lengthy list of classic movies, one of his most iconic roles is playing businessman-turned-survivalist Chuck Noland in the 2000 award-winning film, Cast Away. This Halloween season, get your partner to dress up as Chuck. With a prominent baby bump, you can “dress” as Chuck’s beloved friend, Wilson — a volleyball.

To complete this costume, simply sport this Wilson T-shirt. If you’re feeling a bit more adventurous, you can always paint your baby bump white and add a simple face on your stomach with red paint. Don’t worry, you don’t have to be Picasso when it comes to painting Wilson’s face. This design can totally be messy.

We love this pregnancy Halloween costume because it’s a fun way to highlight your baby bump while also showing off your creativity.

Violet ‘Willy Wonka’ Costume

“Violet, you’re turning violet!”

Transport you and your family to Willy Wonka’s amazing chocolate factory this Halloween. Whether you’re inspired by the beloved 1970s classic starring Gene Wilder or the 2005 remake starring Johnny Depp, embrace your inner child and dress as Violet Beauregarde. Take pride in your Violet DIY costume inspired by the hit movie.

We love that you and your family members can dress up as other characters from the movie. Already the proud mom to a little one? Dress your adorable kid up as an Oompa Loompa. If your partner is joining in on the fun, he/she/they can dress as chocolatier, Willy Wonka.

Handmaid’s Tale Offred Costume

If The Handmaid’s Tale is one of your favorite TV shows, dress this Halloween as Offred. With Season 6 on the horizon, the popular television character’s iconic red cape, which is a staple in Gilead, is a great idea for those entering their third trimester.

The oversized cape allows for extra comfort and a loose fit around your bump. Plus, we love that you can layer clothes underneath the outfit for a warmer fit.

“Blessed be the fruit.”

Snowman Costume

The winter season may still be a few months away, but that doesn’t mean you can’t embrace the colder weather. A staple figure during the chilly winter months is, of course, a snowman. This adorable T-shirt costume features the body of a snowman and a cute scarf that will wrap around your belly and accentuate your baby bump.

This snowman costume is great for those looking to dress up for a Halloween work party or to hand out candy to trick-or-treaters. It’s simple. It’s comfortable. So, what’s not to love?

Twin Pumpkins

Are you having twins? Well, show off your double trouble bundles of joy with this pumpkin shirt featuring two jack-o-lantern faces. A great look for expectant mamas, this darling orange shirt makes for a sweet pregnancy announcement costume. Snap tons of pictures dressed as a cute pumpkin, highlighting your oh-so-adorable mini jack-o-lanterns that are on the way.

Ghost Poncho

A good costume doesn’t have to be frightfully expensive. Instead, you can be the cutest ghost in the neighborhood with this spooky ghost poncho. This traditional costume is a total upgrade from a basic bedsheet — you know the one.

We recommend you style this simple ghost poncho with a pair of your favorite black leggings. It’s a great costume for expectant moms during any trimester. Plus, for busy moms or those not into dressing up for Halloween, it’s easy to throw on and does not take a lot of styling or planning.

Avocado Onesie Costume

Slip into this avocado onesie on Halloween night. As the perfect last-minute costume for expectant moms, the avocado pit will highlight your growing baby bump. Embrace the playfulness of this whimsical avocado onesie and zip yourself into this super-soft fabric. Whether you’re going out to a party or laying on the couch waiting for trick-or-treaters, this onesie is a super versatile costume.

Aside from this costume being comfortable, we bet there will be a few chuckles from your friends, coworkers, and family members if you sport this costume on Halloween night.

Hippie Costume Set

Peace, love, and fringe vests — it’s time to party like it’s 1969! Turn back time and embrace your inner hippie in 2023. Though you won’t be attending Woodstock, you can rock a super groovy costume on Halloween. This 4-piece costume set comes with a fringe vest, peace symbol earrings, hippie glasses, and a bedazzled boho headband.

We love that the vest is cropped so the fringe will loosely hang over your bump. This accessories set can be paired with jeans, leggings, and your favorite tank top or tie-dye shirt.

Spaceship Maternity Costume

A new extraterrestrial being will soon crash land on Earth. This adorable maternity spaceship dress is a total alien invasion celebration. With the internet’s obsession with Area 51, this super cute silver spaceship dress features an intricate baby alien peeking out from a porthole. We’re sure onlookers aka family and friends will surely snap a lot of pictures of the stunning alien phenomenon.

If your partner wants to join in on the Halloween fun, they could dress as an astronaut to match the spaceship theme.

Snow White Costume

With the enchanting live-action movie ready to hit theaters in 2024, get ahead of the Snow White movie trend with this handmade gown. The jersey knit dress features your choice of a royal blue sweetheart neckline or straight top and a bright yellow skirt. The soft stretchy fabric is totally breathable and will accentuate your bump.

A beautiful costume for any expectant mom, this dress is certainly a dream come true.

Grinch Ugly Christmas Sweater and Grinch Mask

There is nothing mean-spirited about this costume. For some Halloween fans, it is the most wonderful time of year. But on Oct. 31, you may want to embrace your inner, well, Grinch. The fun-loving costume is a great idea for those who love Christmas and can’t wait to break out the tinsel.

So, embrace the holiday classic figure by wearing an “ugly Christmas sweater” similar to the one Jim Carrey’s character wears at the Whoville holiday party, and a Grinch mask. If you don’t mind face paint, you could always slap a bit of green on your skin as a little DIY project.

Pokémon Poké Ball Costume

“Gotta catch 'em all!”

If you have a big group or family, this one-size Poké Ball costume is perfect. With a variety of different characters and Pokémon creatures within the video game universe, someone in your group can easily dress as Pokémon Master Ash Ketchum while others dress up as iconic Pokémon such as Pikachu, Charizard, Squirtle, and others.

This group costume idea is great for families with young kids or adults. Plus, the Poké Ball tunic will comfortably fit around your baby bump.
