Princess Diana's 'Revenge Dress' — a Sotheby's auction lot

Princess Diana is pictured in the black off-the-shoulder gown that became known as her 'revenge dress'. The look is completed by a multi-strand pearl necklace with a sapphire pendant and diamond earrings. This very outfit, worn in response to Prince Charles's public admission, is now set to be sold at auction by Sotheby's.
