40 Easy Maternity Halloween Costumes That Make the Bump the Star of the Show
From famous characters to punny getups, these pregnancy-focused costumes are tons of fun!
Clever Halloween costumes come and go every October. But the chance to knock it out of the park with a great maternity costume? That only comes along every once in a while.
And sure, any costume can be a maternity costume if you're pregnant. But there are some out there that are extra great because they put the bump front-and-center and celebrate the newfound milestone in your life. These are some of the best pregnant Halloween costumes of 2023 — the ones that make the most of the pregnant status.
Some outfits inspired by pop culture and feature some of our favorite pregnant characters from TV and movies (like Fargo or Juno). There are lots of cute ideas that are a play on different expressions for pregnant, like "preggo" or "bun in the oven" if you're into some punny ideas. And since it's rare that you can re-use or recycle a maternity costume, there are plenty of ideas that you can make using items of clothing you already own. These are a win-win-win, since they're inexpensive, easy to DIY at the last-minute and often very comfy (very important). Pick your favorite, and your bump will be the star of the night.

Lumberjacks Costume
If you're looking for a couple's costume, you can go as a pair of burly lumberjacks. The great thing about this outfit is that you can probably put it together with items you already have in your closet (and it's probably pretty comfortable to wear).
Bop It Costume
The woman in this photo is not actually pregnant — she's using a styrofoam sphere for that bump — but with a few modifications you can bring back this '90s toy classic for your maternity costume. Just make sure other Halloween revelers do not, in fact, bop you.
Midge Costume
Hi, Barbie! Fans of this year's Barbie movie have already been reminded of Midge, the "pregnant" doll who came with a baby inside a magnetic, removable womb. (In the film, she's played by Emerald Fennell.) Celebrate Midge's 20th-ish anniversary and all things Barbie Land with Midge's signature maternity look. All you need is a floral dress with a purple ribbon and a long wig with two braids — purple jelly wedge heels optional. (You are pregnant after all, and those do not look comfortable.) And, if you want to make it a family Halloween costume or group costume, you'll be tickled to know that Midge sometimes came packaged with Allan (shown here in an easy-to-find blue flannel).
Bun in the Oven Costume
You can DIY this punny costume out of a cardboard box and make it a "boxtume," or you can buy the whole thing outright. Then, if you also want to make it a couple's costume, you can bring the baker along with you. Either way, that bun is cooking!
Pearl and Shell Costume
You can fulfill all your enchanted-under-the-sea dreams with this costume, where your bump stars as a precious pearl. You can re-use the foam board clamshell if you ever want to be Venus, too.
Peas in a Pod Costume
The base of this costume is just a bright green tank top (or t-shirt, or long-sleeve shirt, depending on the weather in your area) — so easy! You can have a lot of fun making different facial expressions on the different "peas" in this pod, too.
Winnie the Pooh Costume
This is the costume that'll won't have you saying, "Oh, bother." You don't even need any "hunny" to make it.
Ursula Costume
On the heels of this year's The Little Mermaid remake, Disney fans will thrill at the chance to wear this Ursula costume, since she's a classic villain with loads of personality. Just note that, if you attempt it, you can't forget the importance of ... body language.
Thor Costume
Thor may have gotten his godly figure back for Thor: Love and Thunder, but if you're looking to dress as one of Earth's Mightiest Heroes while you're pregnant, the gone-to-seed version of Thor from Avengers: Endgame is a good match for a big belly.
Avocado Costume
To craft an avocado where your belly is the pit, simply trace the shape on a large piece of presentation board and then cut out a hole for the "pit." Then, paint it with different shades of green with paint. Attach straps to the back to slide your arms through, and then wear a brown shirt underneath.

Marge Gunderson From 'Fargo' Costume
Oh yeah, if you're looking for a costume that'll keep you toasty warm, this Fargo star is it. The hat with ear flaps is most important, and then you can pull together a uniform to wear under your puffy coat.
If you're not feeling up to go all out, throw on this comfy, ruched Jack o' lantern maternity t-shirt. You can go for the classic orange, or get a spooky black version.
Pasta Sauce Costume
When you're preggo, you go as a jar of Prego! Bonus if you can get a partner or a buddy to go as spaghetti.
Ice Cream Sundae Costume
There's no sweeter costume than this. And while the dress with the sprinkles and the chocolate sauce is cute and clever, the hat literally is the cherry on top.
The "Babydook" Costume
The Babadook is basically a movie about the horrors of parenthood anyway. Lean into your newfound status by dressing up as a "Mamadook," "Babadook" and "Babydook," which is somehow both scary and hilarious.
Milkman and Housewife Costume
Sure, there's some old-fashioned bawdy innuendo behind this costume, but it does give you a good excuse to break out your pearls and vintage-style dresses. It's definitely an easy one to DIY at the last minute.
"Here Comes Trouble" Costume
The shape of the "Pop-o-Matic" Trouble bubble is a perfect match for a pregnant Halloween costume. Just make sure that no one actually tries to press it.
Pregnant Skeleton Costume
Think of this one as another ultrasound photo, only with a spooky twist. (But how did the red bow get in there?) And to up the comfort factor, you can wear this look with sneakers (especially if you have black Converse).
Cat With Yarn Costume
Create your own spin on the classic cat costume by adding a "ball of yarn" to your baby bump. Start by looping the yarn over and over into several loops — don't worry about it being perfect, the idea is for it to be messy. Then pin the ends of the loops onto your shirt to create a "ball" effect, and let the rest of the yarn spill out for you to play with.
Magic 8 Ball Costume
This mother-to-be actually made a Magic 8-Ball costume that gives responses to questions! How'd she do it? Ask again later (or click the link below).
