Dandy
The model, or archetype, of a dandy was Beau Brummell from the Regency period of George IVth. He was a friend of the then Prince of Wales. Lord Byron is also an example. The writer Oscar Wilde is another, later example. Less extreme versions were the American artist who lived in London, James McNeill Whistler, and the French composer Maurice Ravel. The Scarlet Pimpernel is a famous example from literature.
