Who Invented It: King Charles II
Year Introduced: 1666
The modern suit is a derivative of the "lounge suit" popularized in the Edwardian era and the late 19th century. That traces its origins to King Charles II, who decreed in 1666 that all men in the English Court should wear a long coat, a waistcoat, a cravat (a precursor to the necktie), knee breeches (trouser ancestors), wigs, and hats. Obviously, the styles have changed dramatically, but the basic outline was there. British dandies like Beau Brummell helped popularize the style, as well as grooming practices like bathing daily.
