The pregnant skeleton maternity costume is one of my favorites, showing the skeleton of the fetus tucked inside of the mother. My friend made her own a few years ago, but Amazon is selling these Halloween Non-Maternity Pullover Hoodie Costumes for just 34.50. Since they aren’t specifically made to accomodate pregnant women, you’ll have to be early enough in your pregnancy for these to fit well.
If you’re showing a bit more, you can go for the maternity-sized skeleton and baby t-shirt, which is equally clever and a bit roomier in the belly region.
Of course thrift shops have incredible options beyond just the costume section. Rebecca scored this “Pregnant Eighties Lady” item in the dollar bin of her local secondhand store. Doesn’t she look dashing?
