The biggest auction of Diana memorabilia since the late British princess sold dozens of outfits months before her death gets underway in California this week, featuring a midnight blue tulle dress and a flamenco-style lace-up number.

Nearly 50 pieces, including gowns, shoes, handbags and hats, will go under the hammer in Beverly Hills.

A dress worn by Diana, Princess of Wales in 1985 has been sold at auction for 11 times its estimated price, BBC has reported.

The black, ballerina-length velvet evening dress was sold at Julien's Auctions in Hollywood for a total of $1,148,080. It has broken a new fashion record as the most expensive dress, worn by Diana, sold at auction.
