It is arguably the most famous little black dress in history — and after nearly three decades out of public view, it is coming back to the spotlight. Princess Diana's "Revenge Dress", the off-the-shoulder black silk gown designed by Greek designer Christina Stambolian, will be sold at Sotheby's in New York on December 9, 2026. The auction house estimates it will fetch between $150,000 and $300,000 — though Diana's enduring pull could push the final bid well past that.

The Dress That Said Everything Without a Word
On the evening of June 29, 1994, Diana arrived at a Vanity Fair gala dinner at London's Serpentine Gallery in a fitted black cocktail dress — bare shoulders, a bold hemline, a pearl choker, and scarlet nails. It was a striking choice. At the time, royal convention tied black to mourning and funerals, so a princess wearing it to a public event was, in itself, a quiet act of defiance.
But it was the timing that turned a dress into a headline. That same night, a television documentary aired in which her husband, then-Prince Charles (now King Charles III), publicly admitted he had been unfaithful during their marriage. While the nation watched that confession, Diana was photographed looking radiant, composed and utterly in command. The press instantly christened it the "Revenge Dress."
Fashion can be a language when words fail or are simply not enough. Princess Diana understood that instinctively — on her own terms, she turned the dress into one of the most powerful messages she ever made.

Here's a detail most people don't know. According to the Financial Times, Diana had originally planned to wear a Valentino gown that night. But the fashion house reportedly issued a press release describing her outfit to the media before the event — and a frustrated Diana refused to be dressed by a headline.
So she reached back into her wardrobe and pulled out the Stambolian dress — a piece Sotheby's says she had owned for three years without ever wearing it in public. A last-minute switch, born of irritation, became one of the most iconic style statements of the 20th century.
💡 The irony: A dress meant to stay hidden in a closet became the single most photographed outfit of Diana's life — precisely because she chose it in a moment of defiance rather than for a planned appearance.
Inside the Sotheby's Sale — And Its Global Farewell Tour
The gown will headline a standalone fashion evening sale during Sotheby's Luxury Week. Before it crosses the block in New York, fans around the world will get a rare chance to see it in person, as it travels through four Sotheby's galleries.
Where the Money Goes — A Charitable Full Circle
This isn't the first time the dress has changed hands for a good cause. It was last sold in June 1997, when Diana famously auctioned 79 of her dresses to raise money for breast cancer and AIDS charities — a landmark sale reportedly encouraged by her son, a young Prince William.
Now, keeping with that spirit, a portion of the proceeds from the 2026 sale will be donated to the NHS Lothian Charity, on behalf of the Royal Edinburgh Hospital. A rare catalogue from the 1997 charity auction — reportedly signed by both Diana and Christina Stambolian — is also said to be offered alongside the gown.
