Even though i wore clothes underneath, this costume worked perfectly. i'm not a thing person (size 14) and was able to wear this over a long sleeve shirt, hoodie and 2 pairs of pants. (halloween was freezing!) if i didn't have 3 kids and maybe didn't look like i have 3 kids lol, then maybe i'd wear this with my husband out for a costume party. but since i had to dress pg, it worked out with layering.
