This is denim-style fabric, but it's stretchy. It's a free size, but the design is loose, so I think it would fit up to a size L. There are no noticeable stains, but please understand that this is a used item before purchasing. I have other items for sale as well. I will offer a discount if you purchase multiple items, so please take a look if you'd like. Search terms: American Rag Cie, short sleeves, jeans, cut and sew
