A Catherine Walker burgundy crushed velvet evening gown, worn for a State visit to Australia and to the film premiere of 'Back to the Future,' 1985, labelled 'The Chelsea Design Co Ltd', bias-cut with converging seam points at the front waist, the neck cut high at the front, low V-back with shirred gathers below and large shot-silk taffeta bow, leg of mutton sleeves, bust approx 86-92cm, 34-36in, waist 69cm, 27in When Princess Diana wore this dress in November 1985 to Government House in Canberra, she accessorized it with the famous Spencer tiara. This gown was worn in January 1985, to the film premiere of 'Back to the Future,' where she accessorized it with a long rope of pearls knotted at the back and a pair of droplet earrings - which was much-photographed. However, she later complained that although the necklace looked very chic, that the knot dug into her back during the film!
