Diana's Revenge Dress Goes to Auction in December, for the First Time in Three Decades

The black off-the-shoulder dress Princess Diana wore to the Serpentine Gallery in June 1994 is going to auction. Sotheby's will sell it in a standalone sale on December 9.

The estimate runs from 150,000 to 300,000 dollars. Proceeds go to the NHS Lothian Charity on behalf of the Royal Hospital of Edinburgh.

It has not been sold since 1997, when Diana included it in an auction benefiting cancer and AIDS charities, and its current owners acquired it. She died two months after that sale, in a car accident in Paris, aged 36.

Why it is called that

She wore it once.

The evening she chose it was the evening her former husband, now King Charles III, confirmed in a television interview that he had conducted an extramarital affair with the woman who is now Queen Camilla.

Charles is 77. Their sons, Prince William and Prince Harry, were 15 and 12 when their mother died.

A photograph of a woman arriving at a gallery in a short black dress on the night her husband admitted adultery on national television did not require any interpretation at the time, and has not since.

The dress was not the plan

The most interesting part of the story is that it was almost not worn at all.

"The story behind her wearing the revenge dress is quite interesting," the royal expert Claudia Joseph said in 2023. "She'd gone into Christina Stambolian dress shop with her brother Charlie Spencer, and he sat there while she tried on clothes."

Diana had originally ordered the dress in white. The designer disagreed and thought it would work better in black.

"She was groaning about it, but Christina insisted, this looks fabulous on you," Joseph said.

Even then it was not the intended outfit for the Serpentine. Diana had planned to wear a Valentino gown, and details of it leaked to the press in advance.

"She got quite angry about that, so she went into her closet and her butler suggested she wear the Stambolian," Joseph said, "and it of course got dubbed the revenge dress."

What the anecdote changes

Two accidents produced the most analysed dress of the twentieth century.

A designer overruled a client on colour. A leak forced a last-minute substitution, and a member of staff made a suggestion. Neither was a strategy.

That is worth holding onto, because the dress is usually described as a masterpiece of deliberate messaging, and the record suggests it was closer to improvisation under pressure. What Diana actually did was choose well, quickly, on a night she had every reason not to be thinking clearly.

What it is worth now

An estimate of 150,000 to 300,000 dollars is, on the face of it, conservative for the most recognisable dress of its era.

Auction estimates are set to encourage bidding rather than to predict it, and a standalone sale, rather than a lot within a larger auction of royal material, signals that Sotheby's expects this to run well past the top figure.

The charitable destination also matters to the result. Buyers behave differently when the money goes to a hospital, and the provenance here is unusually clean: Diana sold it herself, for charity, three decades ago.

That 1997 sale is part of why this particular garment carries what it does. She was not disposing of a wardrobe. She was converting it, deliberately and publicly, into money for cancer and AIDS charities at a point when the second of those was still difficult for public figures to associate themselves with.

Which gives the December sale a symmetry. A dress bought in a shop on an ordinary afternoon, worn once out of irritation, sold by the woman who wore it to fund medical care, and now being sold again to fund a hospital. Very little of that was planned. All of it turned out to be the point.
