This dress can be worn as a lounging / hostess dress or as a robe. It is made out of the same type of nylon material that a lot of lingerie is made of. The tropical print and bright colors are great and are very reminiscent of the 70's. There is no size label but it looks to be a Medium. The flat measurements are as follows: Armpit to armpit 38", Waist 31", Hips 38", Length from back of neck 53.50", Sleeve 21" and Across back of shoulders 17.25". There is a 21" zipper down the back. Very nice condition.
