Black jumpsuit

Black jumpsuit, bought from a boutique in Philly and wore once. It is cropped at the bottom. For reference, I’m 5’8” and the hem hits my lower calf. It’s also low cut at the armpits (side boob). Very chic with a heel. It’s missing a size tag. I’m typically a medium or 6-8 in dresses (b cup), and it fits snugly on me.
