The biggest auction of Diana memorabilia since the late British princess sold dozens of outfits months before her death will be 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 be auctioned in Beverly Hills.
"Princess Diana's Elegance & A Royal Collection" brings together some of the style maven's favorite designers, including Victor Edelstein, Murray Arbeid and Catherine Walker.
Highlights include Arbeid's blue diamante ball gown, which the princess wore in 1986 to the London premiere of Andrew Lloyd Webber's "The Phantom of the Opera," and a magenta lace dress by Edelstein.
Both pieces are expected to fetch up to $400,000, according to Julien's Auctions, which is running the sale.
"We are here celebrating Princess Diana's elegance," said Gabriela Schwartz of the auction house.
"We have some really standout pieces that Diana wore with a lot of pride and (which are) really emblematic of her style."
Diana married Britain's now-King Charles in 1981 in an opulent ceremony watched by tens of millions around the globe.
The fairy tale soured over the following years and their tempestuous relationship became fodder for newspapers and gossip magazines, feeding a growing celebrity culture that exploded in the 1990s.
The couple had two children – Princes William and Harry – but divorced in 1996 in a tabloid frenzy and amid mutual infidelities.
Diana died in a car crash in Paris the following year as she and her lover tried to outrun paparazzi.
Over a quarter of a century, the woman dubbed "The People's Princess" remains unmatched as a celebrity and style icon whose allure fascinates millions.
A dress worn by the princess that was auctioned last year fetched a staggering $1.14 million.
The collection, which has toured the globe for months, is expected to generate huge interest by the time bidding closes on Thursday.
The sale will include items of high couture, shoes by Salvatore Ferragamo, Kurt Geiger and Rayne, letters in Diana's own handwriting and a number of other items connected to the British royal family.
