Obsessed with the Barbie movie? Us too! You may not be able to pull off a “stereotypical” Barbie costume this year, but you can certainly dress up as Midge the pregnant doll. Yep, that’s right Mattel actually released a doll with a magnetic bump that fit a tiny baby inside. This slightly creepy character is the perfect maternity Halloween costume for moms in the making.

Juno and Paulie costume

For a healthy dose of nostalgia go for a costume inspired by the classic teen movie Juno. To get the look, wear a striped orange tee under a dark hoodie and layer a skirt over denim jeans (trust us, this was stylish in the noughties). It’s easy to find Paulie’s running gear online, but your partner can also DIY it with a maroon tee, yellow shorts and sweatbands, of course.

Tweedledee and Tweedledum costume

Couples pregnancy costumes are just so charming, and none more so than this creative Tweedledee and Tweedledum look. Nail the look with some super-stretchy red leggings, long-sleeve yellow shirts, matching blue bow-ties and red caps with a homemade flag stuck on the top. Mom’s bump will do most of the work for her, but Dad may need a little extra padding to nail the look.

Fortune teller costume

Our prediction? This maternity Halloween costume is going to have everyone in awe. With black flowy clothes, some on-theme accessories and a glowing “orb,” this is an easy DIY costume for pregnant women.

Kangaroo and baby joey costume

It won’t be too much of a stretch to pull off this cute mama kangaroo costume—after all, you’re already carrying around your baby. Toss on some kangaroo ears, a onesie and slip in a plush baby kangaroo and you’ll have everyone aww-ing.

Magic 8 Ball costume

Your belly is the perfect shape. When strangers ask “Is it a boy or a girl?,” just tell them: “Better not tell you now.” It’s a breeze to make your own Magic 8 Ball with a white paper plate or some cut-out felt on a black dress.

E.T. and Elliot costume

Nostalgic Halloween costumes for pregnant women are always winners. That’s why we love this epic look from everyone’s favorite classic movie E.T. the Extra-Terrestrial.

“Bump Ahead!” construction worker costume

Pregnancy can be a bumpy journey sometimes. Make a “Bump Ahead” road sign out of construction paper and stick it prominently on your belly. Wear a high-visibility vest and use yellow or white tape to create lines on gray or black leggings to complete the highway look.

Kitty and ball of yarn costume

This is the purr-fect maternity Halloween costume for those who love cats and DIY getups. Thread yarn through a black shirt, add some kitten ears and whiskers and—voila—you’re a cute cat batting a ball of string.

Golden snitch and Harry Potter costume

It’s Harry Potter and the Golden Snitch—appropriate, since your baby bump is the most important ball of the lot. Get your partner or kid to accompany you as the boy wizard, and you’ve got yourself a magical maternity Halloween costume.

Octopus costume

This too-cute aquatic costume gets eight thumbs up. Toss on a tentacle tutu and smiley face T-shirt (props if it has an expression as silly at this one), and your hunt for the perfect pregnant costume is done.

Cow costume

Talk about udderly adorable! Milk this pregnant Halloween costume idea for all it’s worth—add pink and black felt patches to a black tee and accessorize with a cow-bell and best in show pin.
