Beau Brummell, born as George Bryan Brummell (7 June 1778 – 30 March 1840(1840-03-30) (aged 61), was the arbiter of men's fashion in Regency England and a friend of the Prince Regent, the future King George IV. He established the mode of men wearing understated, but fitted, tailored clothes including dark suits and full-length trousers, adorned with an elaborately-knotted cravat.
Beau Brummell is credited with introducing and establishing as fashion the modern man's suit, worn with a tie. He claimed to take five hours to dress, and recommended that boots be polished with champagne. His style of dress is often referred to as dandyism.
