Diana wore this black velvet gown in the iconic Vanity Fair photo-shoot, shot by Mario Testino at Kensington Palace, in 1997. Its bodice and neck straps are covered in black bugles, and black beads line their edges. Diana looked picture perfect, which matched Walker’s vision. “The inspiration for the embroidery originated from an antique picture frame which was finished with exquisite marquetry edged in ‘lead shot,’” Walker wrote in her autobiography. “I thought it made a pretty picture frame and here in the dress it frames the face and neck.”
