Liked the idea of a shorts style onesie. Ordered the 16 as I wanted it loose so that it dropped off my shoulder like the model. I’m broad shouldered & take a HS size 18 on top as have large bust. I’m only a size 14 on bottom half. I know this style would be generous hence ordering a 16. It was still way too big! I might reorder it in a size 14. I’ve sent the size 16 back.
