Rock This Spooky Season With These Pregnancy Costume Ideas 

The leaves are changing, (decaf) pumpkin spice lattes are back, and fall is in the air. You know what that means: it’s time to start planning your Halloween costume. Whether you spend the night at home passing out candy or trick-or-treating, it’s always more fun when you’re dressed up! We’ve gathered our favorite Halloween pregnancy costume ideas to give you a jump start on your look for this spooky season.

Creative Halloween Costumes for Pregnant Moms

You may have a little more to dress up this year, but that’s no reason not to strut your stuff on Halloween night! These 5 pregnancy costumes are sure to shine a spooky spotlight on you and your unborn baby:

Happy parents and children preparing for Halloween as a family

Avocado Costume

Show off your love for this yummy green superfood this Halloween with a DIY avocado costume. The idea is simple enough: you’re the avocado, and your belly is the pit. Cut a large avocado shape from cardboard and paint it two-toned green. Then, cut a hole about the size of your bump for the “pit.” Wear a brown shirt, hold up the cutout avocado, and let your belly poke through the hole. Voila! Good enough to eat.

Yarn-Crazy Cat Costume

Remake the classic cat costume this Halloween to show off your pregnancy bump. This outfit is super simple — all you need is a black dress or shirt, a ball or two of yarn, and some cat ears. Loop the yarn over the belly of the dress or shirt until it looks like a messy ball, and pin the loops in place. Remember, it’s supposed to look like a cat got tangled up in the yarn. So, the messier, the better!

Mother Nature Costume

There’s no better time to channel Mother Nature than during pregnancy! You’ll need to bring out your inner Greek goddess for this fun costume. Wear a toga that leaves your belly exposed, and paint your stomach to look like the Earth. (You can also paint and wear a nude tank top under your toga for the same effect.) Then, twirl some fake ivy around your arms, put on a flower crown, and you’re ready to go! 

“Mummy” Costume

Another pun-tastic costume! Dress up as a mummy-to-be this Halloween by donning a close-fitting shirt and leggings, then wrapping your body loosely in gauze. This is a particularly fun way to announce your pregnancy to any friends or family that haven’t heard the news yet!

Kangaroo Costume

You’ve already mastered carrying your baby in your belly. Why not show off your skills with a mama kangaroo costume? These onesies are easy to find, thanks to Pam rocking this pregnancy costume in season 6 of The Office. And, let’s be real, comfy pregnancy costumes are everything.

T-Shirt Costume Ideas for Expecting Mothers

T-shirt costumes can be an easy, affordable way to show your Halloween spirit without the pressure of putting together an elaborate look. Here are a few of our faves:

  • Winnie the Pooh: Wear a short-sleeved red t-shirt over a long-sleeved yellow one, and you’re done! Bonus points for carrying honey around with you.
  • Thing One and Thing Two: These t-shirts are labeled with “Thing One” over your chest and “Thing Two” over your bump.
  • Fish Bowl: Use pregnancy-safe fabric paint to create a colorful fish bowl on the belly of a plain black shirt.
  • Pumpkin: Wear an orange shirt with a pumpkin drawn over your belly. Jack o’ lantern face optional.
  • Ice Ice Baby: This one's for all the ‘80s and ‘90s kids. Any shirt will do. Write “Ice Ice” on the chest with an arrow pointing to your baby bump. Get it?
  • Ghost: A Halloween classic; easy, cheap and in season. An old white sheet will do the trick (pun absolutely intended!)
