One fun thing about being pregnant is that you can dress the bump too. After all, celebs like Rihanna, Ciara and Kali Uchis have made their bellies the focal point of their outfits throughout their pregnancies. And with spooky season coming up, what better way to highlight the fact that you have a “bun in the oven” than with a pregnant Halloween costume.
Just a little creativity can go a long way when it comes to dressing around our bump. Instead of trying to hide your growing belly, it's so much easier (and more fun) to use it to your advantage. Several of the options below come from witty puns or make great couples outfits for the mommy and daddy to be. Meanwhile, others are affordable maternity costumes that you can buy last minute or easily DIY with materials you likely already have at home.

Lady Bug and Daddy Long Legs
Not much is needed to pull off this cute Lady Bug look. Just dress yourself in all black, formfitting pieces to show off your bump, then throw on a red poncho and rain boots. Leave the poncho open and add on black dots for the full look.
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 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 it.
Midge Costume
Hi, Barbie! Fans of the Barbie movie have already been reminded of Midge, the "pregnant" doll who came with a baby inside a magnetic, removable belly. To recreate Midge's signature maternity look, you need 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 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). You can have a lot of fun creating different facial expressions for each of the"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 Disney's The Little Mermaid remake, fans can easily recreate this Ursula costume with a maxi dress, wig and body paint. 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 your tummy. Then, paint it with different shades of green. 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, 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 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.
Think of this one as another ultrasound photo, only with a spooky twist. 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.
