Princess Diana's Iconic 'Revenge Dress' Could Sell for Up to $300,000 as It Hits Auction Block for First Time in 30 Years: Report

One of the most famous little black dresses in history is up for auction.

Princess Diana's black silk, off-the-shoulder Christina Stambolian design, better known as her "revenge dress," is going up for sale for the first time in 30 years and will headline a fashion auction at Sotheby's New York on December 9.

The statement piece is estimated at $150,000 to $300,000.

The late royal, who died at 36 in 1997, wore the mini dress while attending a Vanity Fair party at London's Serpentine Gallery in June 1994.

The sultry strapless piece was a last-minute change, as she was originally due to wear a more traditional Valentino gown.

Diana had owned the mini dress for more than three years, but had considered it "too daring" for a public appearance. However, the princess decided "the time was right" to wear it, with her stylist at the time noting that Diana wanted to "look like a million dollars."

The figure-hugging dress was paired with red nail polish, black tights, a Salvatore Ferragamo clutch and a statement choker made from an antique diamond brooch given to her as a wedding gift by the late Queen Elizabeth.

The night was particularly notable as Prince Charles, whom she had been separated from for nearly two years, was set to admit on national television that he had been unfaithful to her with his now-wife, Queen Camilla.

The news was leaked to Diana's team days earlier, giving her time to prepare for the inevitable media frenzy that would follow Charles' confession.

Royal family members were reportedly prohibited from wearing all-black outfits unless they were in mourning, only further driving home the message, per Vogue.

Diana reportedly wanted to order the dress in white, but was convinced of the darker shade after the designer thought it "would look better in black."

"She was [groaning] about it, but Christina insisted, 'This looks fabulous on you,'" royal expert and author of Diana: A Life in Dresses, Claudia Joseph, told Us Weekly in 2023.

Joseph explained that on the day of the Serpentine Gallery event, the press leaked details of Diana's planned Valentino look, forcing her to change her plans.

"She got quite angry about that, so she went into her closet and her butler suggested she wear the [Stambolian], and it, of course, got dubbed the 'Revenge Dress,'" Joseph claimed.
