Unique Retro Cocktail Dress

Up for your consideration: 1960's Holiday/Cocktail Dress The dress is very elegant; it has a bateau neckline, a narrow frame bodice, and a drop waist. My grandmother made this piece, so it has no tags. Since she was a size 4-8 ( 5'10") I would venture that the dress is a Small. The material is silky, and taffeta-like-- I believe that it's really a good weight polyester. Please see pics for condition and measurements. Happy Poshing!
