KENSINGTON Palace has rescued one of Princess Dianas most exquisite evening dresses following revelations that some of her favourite designer outfits have ended up being hawked around downmarket casinos and conference venues. Historic Royal Palaces paid 25,000 for the pink Zandra Rhodes chiffon gown, decorated with rhinestones, crystal beads and pearl droplets, which she wore at a 1986 State Banquet in Kyoto, Japan, and is now being carefully stored in their archives. The Mail recently revealed how Dianas iconic wedding dress was being displayed in a travelling exhibition, last seen at a downmarket casino complex in Connecticut. Other dresses famously first sold off by the princess shortly before her death to raise money for her favourite charities. Now, finally, one of the earliest examples of the princesss growing reputation as a style icon has returned to the royal residence that she called home. MO
