1. Ali Wong

Number one is this suit inspired by Ali Wong. If you’ve ever seen Ali’s standup, you know she’s a total #pregnancymood. Her hilarious stand-up act has inspired thousands of other moms to dress up like her for Halloween. Throw on a cheetah print dress, some red glasses and style your hair in a half top knot. You’ll be wowing all your friends at this year’s Halloween festivities in no time!
2. Pregnant Kool Aid outfit

Do you love to crash parties? A maternity aid outfit can be just for you, mom! All you’ll need is a red t-shirt, black paint, and a cardboard brick wall. This outfit is so much fun and a hilarious way to show off your bump! It will have you going “OHHHH YEAHHHH” all night long.
3. Shark bait
This may not technically be a maternity outfit, but it definitely deserves an honorable mention. We love this baby shark costume paired with the shark bite victim. If you’ve ever breastfed, we know you can totally relate. We like to think of it as ‘love at first bite’. All you’ll need is a white top of your choice and some red paint. “Alexa, play baby shark!”
4. Doll Troll

Who wasn’t obsessed with Troll Dolls when they were little?! All you’ll need to create this blast from the previous costume is a singlet, some jewelry or some string, and a colorful wig. Don’t want to buy a wig? Well, if you’re like me and haven’t washed your hair since last week..You can also tease your hair until it sticks straight and spray a colorful hairspray to hold your hair in place. Here you go, mom! You are a troll!
5. Wilson From Castaway

Wiiiiillllsssssoooonnnn!!! This is one of our favorite last minute Halloween costume ideas for pregnant women. It only takes minutes to make. Grab a white t-shirt, some red paint, and a pair of black leggings. Need a costume idea for your partner? Have them dress up as Chuck Noland. Everyone will be jealous they didn’t think of this Castaway inspired costume first!
6. Sunny-Side-Up Egg
Feeling confused about what to wear this Halloween? Well, we’re excited to share this awesome costume with you! Go like a sunny egg, mom. Trust us, you won’t regret it. Pick up some white and yellow construction paper from your local craft store. Using the white paper, cut out a large circle (big enough to cover your torso) with a “bump-sized” hole. Then, using the yellow paper, cut out a circle to cover the hole in the white paper. Pair with an all-white outfit and you’ll look like eggs – like a sunny egg with the look.
7. The Grinch Maternity Outfit

Does the thought of having to pick out a suit make you feel good, grey? Or you look at all the other suits out there and think “Hate, hate, hate, hate, hate, hate. Double hate. You’re totally loathed.” Then you’re either the Grinch or a pregnant mom who needs to dress up like him. The Grinch’s maternity outfit is what you’ve been waiting for. To recreate this look, you’ll need a green unit (or an all-green outfit), some face paint, and a Santa hat!
