Countess Mara for Capper & Capper Men's Vtg Blue Plaid Shirt in Plastic Detroit/Chicago The shirt has a casual non-button in color. It looks like a long sleeve, but I can’t tell absolutely sure, unless it is opened or unsealed. I don’t want to do that right now, as this appears to be completely legitimately old. The tag says medium, but I know vintage clothing tends to fit smaller than modern. These is some dust and wrinkles as this was recently pulled out of storage. Please see photos. Please see photos or ask questions. Very rare.
