Beau Brummell, né George Bryan Brummell (7 June 1778, London, England – 30 March 1840 (aged 61), Caen, France), 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, beautifully cut clothes, 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 was known as dandyism.
There are as much as two Brummell movies: this one and this one, and a BBC four series. I’m a big fan of the historical BBC series, usually they’re very accurate and interesting, and beautifully made. You can watch some clips of it on the site!
