Slinky. Shop the Frankie Silk Dress from Reformation, a slim-fitting dress with a straight neckline, spaghetti straps, and a center back slit. Bought on 2/5/26 for an event. Worn for that one evening and has been dry-cleaned, and is ready for someone else. No damage, essentially brand new. Still on their site for $298 (https://www.thereformation.com/products/frankie-silk-dress/1304134LYI002.html). I'm 5'5 for reference. Happy to provide photos if needed.
