I'm a bit over 5' 4", 126 lbs with a straight figure. (My usual size is a 4, sometimes 2.) The jumpsuit is perfect in every way, BUT I can't find a size that fits me appropriately.
Initially I ordered a S, it was loose and flowy, and about 3 inches too long (even though I plan on wearing it with heels, it was a bit loose in the leg and thought it may be too much.) So after contacting customer service, they suggested I hold onto it, an order an XS. I did, and was so excited to try it on. I was surprised, as it was SIGNIFICANTLY smaller - as if there should be a size BETWEEN the S and XS. It fit better, but lost the drapey, flowy fit that I liked, (and there's no way I could wear the S with heels). I'm so bummed. Going to try to figure something out!
