We guarantee this outfit will be one of the most popular pregnant Halloween costume ideas for 2021 - especially following the release of season 4 of The Handmaid's Tale in April this year. A long red dress and white bonnet is all you'll need to emulate one of the Gilead residents from the acclaimed book and hit TV series. And if you're feeling a little bit lazy - you can always pick up the pre-made offering online at Amazon instead.

8. Willy Wonka and Violet Beauregarde
You'll need lots of face paint to pull off this brilliant costume idea - inspired by Roald Dahl's legendary Charlie and the Chocolate Factory. Your bump is the perfect accessory to pull off the character of Violet, who famously balloons into a blueberry after eating Willy Wonka's gum. Have your partner dress up and pose as the wacky chocolatier with you.
9. Winnie the Pooh and Piglet
This adorable Winnie the Pooh and Piglet costume is a simple one to recreate at home. Your bump - covered in a yellow dress - doubles up perfectly as the loveable bear's round tummy. Just add ears, a red t-shirt, oh and don't forget the honey jar!
10. Fortune Teller and her crystal ball
We love the creativity that's gone into this fortune teller and crystal ball look. Think loose baggy pants, lots of gold jewellery and heavy eyeliner. And for a more DIY friendly crystal ball recreation - try wrapping your bump in kitchen foil and securing with tape. Your friends are sure to get the idea.
Dress up as Juno and Paulie Bleeker from the hit 2007 film Juno that made a star of Michael Cera and Elliot Page. We think this is a pregnant Halloween costume idea expectant mums can get on board with, due to the appealing comfort factor of this outfit.
12. 'Bun in the Oven'
An absolute classic. Pay tribute to your own bun in the oven, with this sweet baker costume duo. If you're up to the DIY challenge, check out the Thursday's Child blog (opens in new tab) on how they made theirs. Or save yourself the hassle and order a ready-made version online.
