A hat is a headcovering. It may be worn for protection against the elements, for religious reasons, for safety, or as a fashion accessory. In the past, hats were an indicator of social status. In the military, they denote rank and regiment. There are hats for men and hats for women, as well as hats worn by both sexes. Purveyors of men's hats are called hatters and purveyors of women's hats are called milliners. Source: Wikipedia* Hats as part of academic dress
