This is a very gentle and soft tunic. It's a bit see-through if worn alone. 100% cotton. The size is free, but it's quite loose, and I think even a size L would fit comfortably. I wore it quite a bit because I liked it, so there is some wear and tear. There are no stains. This is a used item, so please purchase it if you don't mind. Please note that recycled materials may be used for packaging.
