LONDON - NOVEMBER 20: Diana, Princess of Wales, wearing a stunning black dress commissioned from Christina Stambolian, attends the Vanity Fair party at the Serpentine Gallery on November 20, 1994 in London, England. The famous black "revenge dress" was a spectacular coup by the Princess, worn on the very evening that Prince Charles made his notorious adultery admission on television.
