Wildfox This Mermaid Likes Cotton Tank Dress - Size Small. Fair pre-owned condition. There is some wash wear. But there is a lot of life left in this one. Would make a great swim cover as well as a cool and comfy summer dress. It's tank style, 100% cotton, dark gray with white graphics, little bit of a drop waist with a full-ish skirt. Approximate measurements: 16 1/2" bust, 17" drop waist (has some stretch), 34" length. B29-3516
