Mary Jane, also known as bar shoes or doll shoes, is an American term for a closed, low-cut shoe with one or more straps across the instep. Classic Mary Janes are typically made of black leather or patent leather, have one thin strap fastened with a buckle or button, a broad and rounded toe box, low heels, and thin outsoles. Among girls, Mary Janes are traditionally worn with tights, pantyhose, socks, or completely without them (on bare feet), and a dress or a skirt and blouse. Boys also wear them, although this is less common and if they do, they are traditionally worn with socks (or without them as well), short trousers and a shirt.
