Trick-Or-Treating for Two: 20 Creative Baby Bump Halloween Costume Ideas!

Calling all boo-tiful mamas-to-be! Halloween is just around the corner, and your growing bump is the perfect accessory for some super cute maternity costumes! Whether you're in the early stages of pregnancy or rocking that full-moon pregnant belly, we've got you covered with creative ideas for memorable costumes that celebrate your journey into motherhood.

This Halloween, let's focus on costumes that not only showcase your bump but also prioritize your comfort and support. After all, growing a tiny human is no small feat, and you deserve to enjoy the festivities without compromising your well-being! 

Ah, the first trimester—when your little secret might still be under wraps, but you're bursting with excitement to share the news! Halloween offers a unique opportunity to announce your pregnancy in a fun and memorable way. Here are some creative costume ideas that hint at your special news:

See what we did there? Dress in all red and accessorize with some strategically placed yarn "noodles." Carry a jar of pasta sauce labeled "Preggo" for a punny costume-centric reveal that's sure to get some laughs!

Partner Costume Idea: Have your partner or a friend wear an apron and a chef’s hat to correspond. 

It’s a classic skeleton costume with a twist! Black leggings, a black shirt (or even a black maternity dress), and white felt bones or white cardstock hot-glued all over make this costume easy to DIY if you’re a crafty mama! Add a tiny skeleton to your abdominal area and see how long it takes people to notice.

You can put this colorful look together by wearing a vertical striped, rainbow top! Wrap a black band around your waist and decorate the top of that band with gold coins (you can hot glue little plastic coins from Amazon or elsewhere). If you really want to go the extra mile for this clever costume, you can hang a few gold coins that are “spilling over” from your waist and tummy using transparent fishing line!

Partner Costume Idea: Have an older sibling who wants to coordinate and celebrate their little bro or sis? The Lucky Charms leprechaun is a great option. 

How’s this for a cute costume, animal lovers? Dress up as a kangaroo and place a small stuffed animal in your "pouch" area! It's a sweet way to hint at the new addition to your family (if they can’t already tell from your pregnancy glow). 

And you don’t have to be a kangaroo, either! This idea also works if you dress up as a dog or cat and put a puppy or kitten stuffie cuddling up on your tummy, too.

It’s a classic! Transform into a walking oven by crafting a cardboard box costume. Add a small window where your bump will be, revealing a cute little bun inside. You could search for a bun, bread, or pastry plush or make the bun yourself as a 2D cardboard cutout—it works either way!

Partner Costume Idea: If you’re looking for a couple’s costume or to coordinate with a friend, consider a baker with a chef's hat and a flour-coated face. 

Remember, comfort is key in the first trimester. Consider loose-fitting costumes that won't exacerbate any queasiness or discomfort you might be experiencing.

As your baby bump becomes more obvious, it's time to celebrate your changing shape with costumes that put your pregnancy front and center. These second and third-trimester costume inspiration ideas aren’t “hinting” at your pregnancy—they’re highlighting it! Here are some fun ideas you can use that put your pregnancy front and center:

2. Juno: Channel your inner Elliot Page with a striped shirt, orange hoodie, and signature attitude. Don't forget the bottle of Sunny D! 
   Partner Costume Idea: A sweatband, athletic wear, and pack of TicTacs make for a great Paulie Bleeker to your Juno! 
3. 
4. Padmé Amidala: Are you a Star Wars fan? If so, you might enjoy dressing up as this courageous queen from a galaxy far, far away! With so many outfits to choose from, you can pick your favorite, whether store-bought or DIY! 
   Partner Costume Idea: A dark-cloaked Anakin is the perfect brooding compliment to your pretty pregnant Padmé.
5. Caroline Forbes: If you love the Vampire Diaries, this might be for you! Even better, you can pull this look off with an empire waist top, a light jacket, and maternity jeans! Add a pair of fake vampire teeth and smear some fake blood on your mouth to really hone in on the character. 
   Partner Costume Idea: A dark button-down shirt, gelled-back hair, and dark dress pants are all your partner needs to pull off the classy, handsome Alaric Saltzman. If you want to go the extra mile, accessorize with a (blunted!) stake.

7. Mother Earth: Drape yourself in shades of blue and green—this might be the perfect opportunity to wear an empire waist floral dress if that’s your style—adorning your bump with small toy animals or flowers. Alternatively, you could wear a white dress (or wrap!) and turn your bump into the Earth! 
   Partner Costume Idea: Have your partner dress in a fiery windswept costume to evoke earth, wind, and fire, or have them wear a star and planet-speckled sweatshirt to act as the space to your planet. 
8. Mummy: This super cute spooky costume can be as simple or complicated as you want to make it! (And it’s a great choice for the “punny” among us!) Wrap up in as many white bandages or soft, bandage-like strips of cloth—but nothing too tight!—with a big pair of googly eyes peeking out of your belly area. 
   Partner Costume Idea: A white button-up, some khaki pants, tousled hair, and a weapon holster make the perfect Rick O’Connell (from “The Mummy”) complementary costume. 
   

1. Mike Wazowski: Go green and turn your belly into the lovable monster's single eye for a Monsters Inc. inspired look!
   Partner Costume Idea: Who better to hang out with Mike than Sully, the lovable, big, blue monster! Your partner can find this outfit or DIY one, as long as it’s blue and has purple spots. Don’t forget the horns!
2. Winnie the Pooh: A red crop top and yellow bottoms transform you into everyone's favorite honey-loving bear.
   Partner Costume Idea: Your friends and family can dress as the rest of the Hundred Acre Wood crew! An orange and black striped outfit for Tigger, all gray (with a “pinned” tail!) for Eeyore, yellow bunny ears for Rabbit, a cute pig nose and fuschia shirt for Piglet, and schoolboy clothes for Christopher Robin…you get the idea!
3. Cat with Yarn: This is a chance to wear a cute, comfy outfit that’s sure to earn you smiles! Turn your tummy into a ball of yarn by hot gluing yarn across the belly section of the outfit of your choice. Complete this look with cat ears, a tail, and some whiskers (you can use eyeliner!) to bring it all together.
   Partner Costume Idea: Your partner or bestie could dress as a giant ball or knot of yarn by wrapping themselves in yarn that matches the color you chose for the “ball” on your costume! Alternatively, they could dress as a cat, too! A pair of ears and eyeliner whiskers can go a long way. 
4. 
5. Miley Cyrus' Wrecking Ball: Dress in black but ensure your belly area is gray. Wear long, silver chain necklaces that extend down to your bump and affix them to the top of the gray area. Add a Barbie dressed in white, sitting on top of your baby bump (you can glue her to the chains and to the “wrecking ball” on your shirt). 
   Partner Costume Idea: Go all-in on Miley and have your besties dress as other Miley eras—Hannah Montana, Dancing in the USA, Blurred Lines, and more! 
6. Death Star: For a humorous twist Star Wars fans are sure to get a kick out of, turn your bump into a Death Star! You can wear a space-related shirt as the “background” to really make it pop!
   Partner Costume Idea: This is a great opportunity for your Star Wars-loving partner to dress up as Darth Vader, Han Solo, or even Luke Skywalker!

1. Avocado (or Any Fruit with a Pit): You could spring for a full-on avocado outfit or wear a green dress with a brown circle on the belly. If you’d prefer to be a peach or a coconut or something else, just be sure you pick a dress that matches the color of the fruit you’re going for! 
   Partner Costume Idea: Your partner could dress as a farmer or gardener, complete with overalls, a straw hat, and some small gardening tools affixed to a belt. They could even carry a watering can or basket of other fruits to complete the look. 
2. Disco Ball: Are you a mama who loves glitz and glam? This is a great opportunity to dress up! Slip (or shimmy) into a silver dress with lots of sparkles!
   Partner Costume Idea: Your partner and/or your besties can dance the night away by dressing like disco dancers! A colorful 70s-style outfit with bell-bottom pants, a wide-collared shirt, and fun wigs easily complete this fun look. 
3. Pumpkin: This classic look calls for orange attire with a jack-o'-lantern face on your belly! It’s perfect for this pumpkin-themed time of year!
   Partner Costume Idea: This is a perfect opportunity to bust out the classic scarecrow costume: a red checkered shirt, blue jeans, a straw hat, and bits of straw sticking out everywhere!
4.  
5. Gumball Machine: There are so many fun ways to go about making this costume! A simple one we like is to wear a white t-shirt with a red tutu skirt. Glue tons of fuzzy, colorful pom-poms glued onto the white shirt’s belly area, and complete the look with a red beret hat or beanie.
   Partner Costume Idea: Glue a few pom-poms to a cheap Halloween wig to make it look like “gum” got stuck in your partner’s hair! 
                            

6. Fishbowl: It doesn’t get much cuter than this! Wear a blue outfit with plastic (you can use plastic wrap or freezer bags!) positioned around your belly. Add a fish behind the plastic, and you’re good to go! 
   Partner Costume Idea: Your partner can dress as a snorkler or scuba diver! They could wear a bathing suit (and might want to wear a rash guard if the weather’s cold) or a wetsuit, complete with flippers and a snorkel mask. For added effect, they could carry a toy fishing rod, playfully trying to “catch” the baby in your belly bowl!

These pregnant belly costumes and couples costumes not only showcase your beautiful bump but also offer comfort and ease of movement. Whether you choose to be a character, a silly reference, or an inanimate object, the key is to have fun and embrace your changing body. Always consider the weather and your plans for the evening when choosing your outfit, and make sure you do what feels right and comfortable for you.

While dressing up is fun, comfort and safety should be top priorities for expectant mothers. Here are some key factors to keep in mind when choosing your Halloween costume:

That’s right! We said it, and we mean it. To stay comfy, take these into consideration before choosing an epic pregnancy costume idea:

Pregnancy can make you feel warmer than usual, so opt for breathable fabrics and layered costumes. This way, you can easily adjust if you start feeling too hot or cold.

As your bump grows, extra support for your back can make a world of difference. So, for those long nights of trick-or-treating or Halloween costume parties, consider maternity lumbar support, mama! We’d say “treat yourself” but really, this is a year-round lifehack. Maternity lumbar support garments are discreet enough to wear under most outfits—including Halloween costumes—and can help alleviate some of the strain on your lower back.

If you're planning to be on your feet for extended periods, remember that compression socks can provide much-needed support and comfort. These support your circulation and come in handy for those chilly Halloween evenings. 

Consider your Halloween plans when choosing your costume:

1. Trick-or-Treating with Older Children: If you're accompanying other little ones, opt for a comfortable costume that allows for easy movement. Think loose-fitting maxi dresses or stretchy materials that won't restrict your stride.
2. Stay-at-Home Celebrations: For a cozy night in, you have more flexibility. Feel free to choose elaborate makeup or accessories that might be impractical for outdoor activities. On the other hand, if all you feel like are maternity jeans and a simple white t-shirt with a pregnancy pun or "baby on board" icon, go for it, mama!
3. Halloween Parties: Strike a balance between style and comfort. Choose comfy, flat shoes with good support (you can break out the high-heels next Halloween), and consider costumes that allow you to sit comfortably.

Avoid tripping hazards like long skirts or capes, and steer clear of masks that might obstruct your vision. And if you're using face or body paint, opt for pregnancy-safe, hypoallergenic options to avoid skin irritation.

It is what it is—frequent bathroom trips are part of pregnancy! Ensure your costume allows for quick and easy bathroom access to avoid any unnecessary stress or discomfort.

By keeping these considerations in mind, you can ensure that your Halloween costume is creative, comfortable, and practical. The best costume is one that makes you feel confident and allows you to enjoy the festivities to the fullest!
