Ribbed short sleeve babydoll dress

Super cute black dress that I bought without trying on and tragically couldn't fit into. Cinched bust with a faux drawstring you can tie into a bow. The waist hits more along the ribcage than the natural waist for a slight babydoll/A-line silhouette. Fabric content: 97% polyester; 3% spandex. Material is ribbed and very stretchy. Measurements: Pit to pit: 15" unstretched (flat) Waist (hits at ribcage): 12.5" unstretched (flat) Shoulders: 12.5" (flat) Total length: 33" Sleeve: 6.5" Tag says medium but it fits more like a small.
