Dress is two layered, the exterior lace is cotton and interior red is a polyester I believe. Feels super silky. Betsey Johnson New York Vintage dresses I think run on the smaller side, not too much give with the fabric. Two silk ribbons attached to make a halter. Side zipper that’s hidden. In great shape no damage no stains of any kind. Size 8 Length: 35” inch Pit to Pit: 16”inch Waist:28”inch Hips:32/33”inch Ribbon/halter:25”inch Measurements taken while laying flat
