This is an open collar shirt from ADRER made of poly-satin material. It's a hybrid shirt that can also be worn as a regular collar shirt since it has buttons all the way to the top. This color is sold out, so I think it's rare. *I am also listing this item on Yahoo Auctions. Once it is purchased on either site, I will delete the product page on the other site. Brand: ADRER Color: Brown Size: M Width: 64.5 / Shoulder Width: 62 / Length: 76.5 / Sleeve Length: 24
