A Vanity Fair blue/purple half slip with ruffles on the bottom. It has some wear and tear with a small hole ( see picture) and the elastic is a little worn. it has a 32” waist and 28” length. I’m guessing that it’s nylon, that’s what it feels like. I’m not sure exactly what time period it’s from. I’m guessing the 50’s . I bought it from a vintage store 30 years ago to use as part of a flapper Halloween costume.
