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:
