Ten iconic evening gowns worn by Diana, Princess of Wales, are set to go under the hammer in March and are expected to fetch up to £830,000.
The lavish evening dresses were originally auctioned off by Diana in New York in June 1997 to raise money for charity. That auction took place just two months before her death.
The latest auction, called "Fit for a Princess", is due to take place at Kerry Taylor Auctions in London on March 19.
The most expensive in the collection is a Victor Edelstein designed midnight-blue velvet evening gown worn by Diana during a White House dinner hosted by President Reagan in 1985.
That gown, which she famously wore as she took to the dance floor with John Travolta, is estimated to fetch between £200,000 and £300,000.
The collection also includes a glittering sea-green sequinned gown, designed by Catherine Walker, which Diana wore during a State visit to Austria in 1989. it is estimated to sell for between £30,000 and £50,000.
The auction house predicts the dresses will go to individual buyers rather than to a single collector.
Kerry Taylor said of Diana, "I think she suffered quite a lot during her life and a lot of people empathised with her situation and the way she, towards the end, she sort of got through it, became empowered ... And I think the dresses show that too".
