1. The ‘Elvis Ensemble’ by Catherine Walker

This dramatic dress and bolero jacket were worn by Diana, Princess of Wales, for an official visit to Hong Kong in November 1989. Diana called it her ‘Elvis Dress’, perhaps because the stand-up collar reminded her of the rock legend Elvis Presley. She also wore it for an official portrait photograph. Encrusted with pearls and sequins, the ensemble was designed by Catherine Walker, the princess’s close friend and favourite couturier.

In 1997, shortly before her death, Diana sold 79 dresses in a charity auction held by Christie's. The proceeds of the auction - over 3 million pounds - went to AIDS and cancer charities. This dress was bought by an American company, The Franklin Mint, which produced Diana memorabilia. They later donated it to the V&A.
