CAVALIER HAT

The cavalier hat was a large hat with a moderate crown and a broad brim turned up at one or both sides, worn by men in Britain during the 17th century. The Cavalier hat was often adorned by a large feather on one side. This style of hat was popular among the Cavaliers of the time, while the rival sugar-loaf hat was more popular among the Puritans.
