Purchased at a used clothing store. It's a Lacoste nylon jacket. Judging by the sleeves, it seems to be unused, and the short length is expected to make your legs look longer. Size is 40, but I think it's about a Medium. Stylish celebrities were all wearing vintage sportswear, so I jumped on the bandwagon and bought it. I'm starting to think it's more for younger people... so I'm selling it.
