dandy, Beau Brummell:

George Bryan Brummell was a trend setter in Regency England and a friend of the Prince Regent. Nowadays we might think of a dandy (a term coined by Lord Byron and describing the club to which Brummell belonged) as being outrageously dressed, but at the time Brummell favored simple but elegant, in some ways severe, clothing of high quality. Dandies were said to devote a lot of their time to their toilet, meaning they were meticulous about grooming, deportment, the cut of their trousers (Brummell favored trousers over breeches) and the polish of their shoes. Think of dandies as the first metrosexuals.
