I purchased a size S, but received a size M. after lots of back & forth with their customer service, I was finally issued a "refund" (that I never received) instead of store credit I didn't want. as far as the jumpsuit goes, I took the loss & stuck with the M because returning it & repurchasing the correct size would've costed more than getting it taken in at the waist. if you receive your correct size, this jumpsuit is SO CUTE. super flattering & I received a lot of compliments. if you're short, you'll definitely have to get it hemmed like I did. I'm 5'2 & even with heels on it was too long.
