Diana dress may sell for STG80,000 A "FAIRY-TALE" dress worn by Diana, Princess of Wales, will go on sale next week and could fetch up to STG80,000 ($A142,900). Auctioned by the same auctioneer that sold the see-though dress once worn by the Duchess of Cambridge, the gown is described as one of the most ornate and romantic of all Diana's dresses. Designed by the Emanuels - the creators of her wedding dress - the frock shimmers with gold sequins, crystals and pearl beads, and comes with matching headband, optional sleeve panels and petticoat. Kerry Taylor Auctions said the dress has a "pretty, fairy-tale princess feel to it" and estimates are set at STG50,000 - STG80,000. Diana first laid eyes on the dress at a Red Cross benefit fashion show in the summer of 1986, and, rather than having it specially commissioned from the designers, she acquired the standard size ten dress from the show. The auctioneer says it "fitted her perfectly" and she went on to wear it on many occasions.
