J. Crew strapless dress

JCrew strapless dress w/ silk sash. Can tie in back or front. Has a built in bra - attempted to show in photo. It’s a beautiful shade of green. 100% cotton outer layer, 100% polyester lining, 100% silk belt. Length from highest point of breast in front straight down to bottom hem is about 29.5”. Measures about 15” across midsection (where sash is tied). Measures about 16” armpit to armpit * it does zipper all the way up. There’s nothing wrong w/ zipper. It just doesn’t quite fit my mannequin.
