  • Catwoman

    This is canonical - at least in a canonical alternate timeline. Batman and Selina Kyle's Catwoman absolutely made the world's cutest bat-cat in 2020's Catwoman 80th Anniversary 100-Page Super Spectacular. And that makes it the ultimate nerdy pregnant costume for this Halloween.

  • The Entire Solar System

    This is truly a galaxy-brained concept - take a classic science fair solar system model and make it fashion. Or at least, make it the perfect pregnant costume for Halloween, with baby-to-be the shining sun like the center of your universe they are.

  • Avocado

    If you're pregnant then you have a built-in bump that's perfect to play the seed in an avocado costume. As simple as a brown shirt (or tummy) and green cardboard cut out into that classic avocado shape, the avocado is a modern classic funny pregnant Halloween costume.

    A lot of pregnancy cosplays are just "[insert character], but pregnant," but the indomitable Marge from Fargo is not only a canonically pregnant character, she's instantly recognizable. Plus, her costume will keep you cozy on even cold weather Halloween nights.

  • Padmé Amidala

    There are endless ways to make your baby bump into a disco ball for a groovy pregnancy costume - the simplest being taking a silver tube top and wearing it over a black shirt or dress. Whether you decide to make the rest of your outfit as funky as your disco baby belly is up to you.
