Princess Diana’s iconic “revenge dress” is returning to the auction block nearly 30 years after it was last sold, giving collectors another opportunity to own one of the most recognisable outfits in modern royal and fashion history.

The black silk dress, designed by Greek designer Christina Stambolian, will be auctioned by Sotheby’s in New York on December 9, 2026. It is estimated to fetch between $150,000 and $300,000, although its cultural significance could push the final price higher. Before the sale, the dress will be exhibited in London, Hong Kong, Geneva and New York.

Diana wore the dress on June 29, 1994, to a Vanity Fair fundraising event at London’s Serpentine Gallery. That same evening, Prince Charles appeared in a televised interview in which he publicly acknowledged that he had been unfaithful during their marriage. Diana and Charles had already been separated for about two years, but Charles’ admission intensified worldwide attention on their troubled relationship.

Diana had originally planned to wear a Valentino outfit to the event, but changed her plans after details of the dress were leaked. Instead, she chose the Stambolian design, which had an off-the-shoulder neckline, fitted silhouette and short, asymmetrical hem. The decision represented a striking departure from the conservative image traditionally associated with the royal family.

The dress quickly became known as the “revenge dress”, although the nickname was created by the media rather than Diana herself. Fashion commentators have since viewed the moment as an early example of “revenge dressing” — using clothing to project confidence, independence or defiance following a difficult personal experience.

Its importance goes beyond the story surrounding Charles and Diana. The dress became an example of how Diana increasingly used fashion to control her own public image. Instead of allowing the televised revelations about her marriage to dominate the evening, her appearance became the major visual story of the night. Sotheby’s has described the garment as an example of fashion crossing into wider cultural history.

Diana eventually decided to sell many of her clothes for charity. In 1997, shortly before her death, she auctioned 79 dresses, raising money for causes including cancer and AIDS charities. The Stambolian dress was sold at that auction and has remained in private hands since then, making its upcoming appearance one of the rare occasions when the public has had a chance to see it offered for sale.

The expected price also reflects the growing value of Diana’s fashion legacy. Her clothing has repeatedly attracted major auction interest. A black-and-blue evening dress designed by Jacques Azagury and worn by Diana sold for $1.15 million in 2023, setting a record for the most expensive Diana dress sold at auction at the time.

Interest in Diana’s style has remained strong among younger generations, with fashion publications and social media continuing to revisit her wardrobe decades after her death. Her ability to combine royal formality with more personal and unconventional choices has made her an enduring fashion reference.
