This is a UNIQLO gray striped short-sleeved T-shirt. The size is men's S, which is equivalent to women's M. It's made of 100% cotton. It can be worn unisex. I haven't worn it much, and I have a similar one, so I hope someone can use it. - Color: Gray - Design: Striped - Sleeve Length: Short sleeve - Material: Cotton Thank you for looking.
