Faithful rendition of the popular blue chambray chinstrap work shirt, circa 1910-1940. 100% cotton. Metal vintage-style buttons. This pairs very well with our embroidered logo patches for a mechanic or gas station attendant look. Durable and meant to be used! Our customers asked for these work shirts to be made roomier, and we listened! These shirts run closer to modern clothing sizes. Please see chart in photos for details.
