17 Scary Good Pregnant Halloween Costumes, Inspired By Moms
Let’s face it, when you’re pregnant, it often feels like you’re already wearing a costume. There are plenty of days when you don’t feel like you’re in your own skin.

Whether you want to put your belly front and center in a funny, creative look, or embrace your spooky side, there are plenty of options for expectant moms who are counting down the days to October 31st. Because you’re never too old to dress up!
A few years ago, my family and I dressed up as matching farmers and my bump looked pretty cute in a pair of overalls. One of our Bump editors even used her Halloween costume to announce her first pregnancy, wearing a skeleton ribcake shirt with a tiny skeleton baby printed over her belly!
