Pregnant Halloween Costumes and Maternity Costumes

Halloween Costume Ideas for Pregnant Women

If this October finds you “with child”, congrats! There are tons of Halloween costumes for pregnant women, so it’s just a matter of finding the one that fits you (and your belly) best. Maternity costumes generally come in two types; the kind of costume for pregnancy (made especially for pregnant women), or costumes that just happen to work really well when you have a bun in the oven. 2008 was the first year that an entire new line of specialty maternity costumes were released, with more coming every year! If you want more variety look for costumes with open waists that cinch with a belt or a high empire waist. Thankfully many Halloween costumes have one of these two forgiving waist styles, and we’ve featured the best of them below. We’ve hand chosen all of these unique maternity Halloween costume ideas just for you and the new arrival.
