I am selling a set of two leggings: a gray Hotcott 10-length legging from Belle Maison and a dark brown legging with a mix of various colors, both purchased online. Both are new and unused, but since I've removed the tags and taken them out of the bags, I've listed them as "Like New." The Hotcott is size 90, made of 95% cotton, and gentle on the skin during the dry season. The dark brown mix is size S, so I think it fits sizes 80-90cm. Suitable for both boys and girls, how about using them as innerwear during the cold season?
