NWOT. I purchased this T-shirt from an organization that trains service animals for veterans. I love this shirt but it’s too big so it’s never been worn. I wasn’t able to try it on when I purchased it. Size is XXL but is more of an XL. Armpit to armpit measures 22 inches; length is 26 inches long. I wear a large and should have bought the XL. My loss, your gain! Happy shopping!
