Let’s face it, when you’re pregnant, it already seems like you’re wearing a costume—there are definitely times when you don’t feel like you’re in your own skin. But who knew your belly bump could be the ultimate Halloween costume accessory? From DIY tricks to hilarious store-bought treats, we’ve scurried up a slew of ideas so moms-to-be can go belly up with pregnant Halloween costumes that are devilishly good.

Easy Pregnant Halloween Costumes

Sometimes you really can pull on a comfy shirt on and call it a night—all you need to do is take fabric paint or marker to a stretchy (preferably cotton) shirt and create whatever maternity Halloween costume strikes your fancy. A few easy maternity Halloween costumes ideas to get the creative juices flowing:
