For much of the 20th century, Duke freshmen had to wear dinks (first a beanie and later a floppy hat) and women a yellow bow. If Duke won the annual Duke-UNC football game, the freshmen and women could discard the bow. However if Duke lost, the bow had to be worn until the end of the first semester.
