Darling black mesh and embroidered lace type cover up by Kivenst. It has a size tag that says F on it, which I believe is pretty much the same as "one size fits most" but probably best for a medium on up. Do see measurements below to help you decide. Its a loose easy fit with half sleeves and a tie under the bust.

Excellent preowned condition. No issues worth noting.

armpit to armpit across bust all round: 54" with the ties tied all the way tight
waist: free
hip: free
length shoulder to bottom hem: 41"

Size: one
