NWT strapless Vera Wang mermaid dress

Strapless iridescent Vera Wang (Lavender Label) dress, new with tags and never worn, purchased on Shopbop a few years ago. Side zipper and a cool knotted bow detail in the back, the bottom of which drapes down to the edge of the dress. Comes to about mid-thigh. Shimmery taffeta fabric and mermaid-like! Size 4 but runs small.
