Here is a sleek sleeveless dress from the 1970s. Feels like mostly or all polyester. Jet black fabric with sharp multicolored striping. 15" zipper down the back. The blouse section is ribbed, the skirt is smooth and slightly sheer. Medium weight, soft, and comfy. It's in amazing condition with tons of life left! Here are the measurements taken laying flat.
