The reason for the strange nickname "Revenge Dress" is simple. While Princess Diana (†36) attended a reception at the Serpentine Gallery in London in June 1994, the documentary by Jonathan Dimbleby, in which Prince Charles (69) talked at length about his affair with Camilla Parker Bowles (71), who is now the Duchess of Cornwall, was shown on television.
Princess Diana in her "Revenge Dress"
Diana knew that Prince Charles wanted to use his confession on television to improve his image among the population. So the day before the newspapers could print the headlines, she visited the reception in the English capital in this tantalizing dress.
Prince Charles' confession, naturally, was THE story in the newspapers the next day. But the picture of Diana next to it did not convey the image of a deceived wife. Quite the opposite even.
