This is a Ralph Lauren men's short-sleeved shirt, size XS, purchased about 20 years ago. It's a size that can be worn by women or older elementary school children. It features hook buttons and a unique design on the chest pocket and back. The tags appear dirty, but it's a processing effect as both are the same color. Made of 100% cotton, so it seems cool even in midsummer. I bought it and my body shape changed immediately, so I've only worn it once, but it has been stored at home for a long time, so please understand before purchasing.
