Lanvin summer dress. Size S, but a bit large, so it should fit those who usually wear S-M size. Back zipper. Length: Approximately 93 cm. It will be below the knee on a 158 cm tall person. Photo 5: It has a lining, so you don't have to worry about it being see-through. There are no stains that I could confirm, but please understand that it has been stored in a chest of drawers for several years before purchasing.
