It's the fashion moment that grabbed headlines and gave the world the term "revenge dressing".
On 29 June 1994, Diana, Princess of Wales wore a black, fitted, off-the-shoulder dress to a fundraising dinner hosted by Vanity Fair for the Serpentine Gallery in Kensington Gardens. As stunning as the head-turning garment was, it had symbolic weight, as Diana wore it the same night then-Prince Charles would reveal his infidelity with Camilla on TV.
