Retro-inspired Steady Clothing Classy Piston Short Sleeve Button Down Shirt. Never worn. Colors are black and Thunderbird blue. Cool piston buttons and V8 emblem on chest. Front chest pockets. Made from polyester so easy machine wash and tumble dry care. See photos for measurements because it is marked a small but it is very generous. I’d say it is a medium. Chest is 23.5" and length 38". Check the measurements on your size Medium shirts - this might be a great fit. Purchased as a gift ( hence the white-out on price tag) and wanted it to go with the Thunderbird, but really needed a different size and they were sold out. Thunderbird not included lol
