Sotheby’s will offer the dress for sale in New York on December 9, 2026, with an estimate of £110,000 to £220,000, which is roughly $150,000 to $300,000.
Ahead of the auction, the dress will begin its international exhibition tour from London during Fashion Week, then move on to Hong Kong and Geneva before arriving in New York.
A night in which the narrative changed
On June 29, 1994, Diana appeared at a charity event held by Vanity Fair magazine at the Serpentine Gallery in London, wearing a short black silk dress with a tight, off-the-shoulder design by Christina Stamboliani.
His appearance coincided with the broadcast of a television interview in which Charles, then Prince of Wales and now King, admitted to cheating on Diana after their relationship broke up.
All eyes were on the interview, but pictures of Diana quickly hit the papers, making the dress, dubbed the “revenge dress” by the media, one of the most famous pieces in royal fashion history.
The name was not given by Diana herself, but appeared later as a media interpretation that she chose a different look than what the public is used to on very sensitive occasions.
Last minute option
A black dress was not Diana’s first choice that evening. She planned to wear a more conservative design from the house of Valentino, but changed her mind after details of the look were leaked to the press.
Instead, she chose an Istanbul dress that had been in her closet for about three years. Diana was previously hesitant to wear it because it seemed bold compared to the traditional constraints of royal fashion.
She finished off her look with red nail polish and statement jewelry, a definite change from her usual image. These details gave it a visual presence that overshadowed the media coverage of Charles’ confession.
Morgan Halim, global head of bags and fashion at Sotheby’s, believes the dress’ significance goes beyond its design, as it represents a rare moment when a piece of clothing became part of cultural history.
According to Halim, Diana used her appearance to regain control of a painful personal narrative, a moment before social media, but she had all the makings of an image that could be shared globally.
From the dress to the phenomenon
Diana’s appearance helped coin the phrase “revenge suit,” which is used to describe a confident person after a breakup or emotional crisis.
The idea was not entirely new, as clothing had long been used to initiate transformation and another phase. But Diana’s image took on this meaning the moment the public understood it directly, and it has been associated with the black dress ever since.
Auction for the second time
Diana first showed the dress at a charity auction in 1997 as part of a collection that included 79 pieces of her clothing, the proceeds of which were raised for organizations fighting cancer and AIDS.
The dress then sold for £39.98, which is close to £100,000 in today’s value. Since then it has remained with the family who bought it without ever being offered for resale.
The dress’s upcoming auction will be accompanied by a rare catalog from the first sale, signed by Diana and the designer, indicating that Prince William had the idea to sell his mother’s collection for charity.
A portion of the proceeds from the new sale will go to a health charity in Scotland to bring the dress back up for auction and maintain the charitable dimension Diana started before her death in 1997.
