Diana’s Revenge Dress Leaves London Today, Bound For A New York Saleroom In December

The last chance to stand in front of the most photographed black dress in British history comes to an end on Thursday. Sotheby’s opened the first public exhibition of Princess Diana’s revenge dress in nearly 30 years on 18 September at its New Bond Street galleries, and the run closes on today before the dress travels to Sotheby’s rooms in Hong Kong, Geneva and New York. It will be offered at auction in New York on 9 December, during the house’s Luxury Week, carrying an estimate of $150,000 to $300,000, which is roughly £110,000 to £220,000.

Viewing has been free, which is worth saying plainly, because a garment of this level of fame normally arrives in Britain behind an exhibition ticket.

The dress had been in a wardrobe for 3 years before anyone saw it

The story that has attached itself to the dress is a story about one night. The making of it happened well before that. Diana walked into Christina Stambolian’s boutique in Beauchamp Place in September 1991, picked up a few pieces, and told the designer she wanted a special dress for a special occasion, that it did not matter whether it was short or long, only that it had to be something special. They settled on black. Two dressmakers then spent more than 60 hours building it by hand.

She had paid £900 for it, and then it hung there. The gown sat unworn in her wardrobe for 3 years. Stambolian said afterwards that 3 years went by without Diana wearing it, and that she eventually realised the Princess had been waiting for the right occasion.

She had been expected in Valentino that evening

Diana had intended to wear a Valentino gown to the Serpentine dinner. That plan leaked to the press beforehand, so she changed course and reached for the dress that had been waiting in the wardrobe since 1991. Paul Burrell later recorded the exchange, with Diana asking him whether it was too much, and then saying “Here goes then, Paul.”

She wore it to a gala at the Serpentine Gallery on 29 June 1994, the same evening a television interview aired in which Charles acknowledged his affair. The following morning she had taken the front pages off him, with The Sun running the line “The Thrilla He Left to Woo Camilla”.

Stambolian herself read the choice in theatrical terms. She compared it to Swan Lake, saying Diana had chosen not to play the scene like Odette, innocent in white, but like Odile, and that she was clearly angry.

What is actually on the rail at New Bond Street

The physical description matters here, since most people know the dress from 3 or 4 press photographs taken in a scrum outside the gallery. It is an off-the-shoulder black silk evening gown with a chiffon train. The bodice is criss-cross pleated, the skirt is fitted chiffon and the train sweeps to one side. Contemporary descriptions of the £900 black silk crepe dress noted the ruched bodice, the asymmetric hem and the side sash.

A catalogue goes with it, and the note inside credits Prince William

The lot is not only the dress. Accompanying it is a rare copy of the original auction catalogue, numbered and signed by both the Princess and the designer, and the catalogue includes a handwritten note crediting Prince William with the idea for the sale.

That sale was the Christie’s New York auction of 1997. Diana put the dress up along with other clothing to raise money for AIDS charities, and it has not been offered publicly since. So the buyer in December will be only the third owner of it, and the second since it left Kensington Palace.

Why the family is selling now

The current owner is Briege Mackenzie, and her reasons have been given straightforwardly rather than through a spokesman. She said that she and her late husband had known the dress was something special, that bidding at auction and winning it had been one of the great days of their life together, and that with him gone, that chapter had closed and so should this one. She added that she hoped it would go to someone who would enjoy owning it as much as they had.

Part of the proceeds will go to NHS Lothian Charity, on behalf of the Royal Edinburgh Hospital.

The estimate looks conservative against what Diana’s clothes have been doing

Here is where the numbers get interesting, because Sotheby’s own recent results suggest the published estimate is a floor rather than a forecast.

• A black and blue evening dress Diana wore to a 1985 dinner sold in 2023 for a record $1.15 million, which was 11 times its pre-auction estimate.
• A red sweater with a sheep design, worn to a polo match, went for $1.1 million, a record for an item owned by the late princess.
• One of her less famous dresses exceeded expectations in 2023 and sold for $604,800.

If a jumper reaches 7 figures, a dress carrying the single most replayed fashion moment of the 1990s is unlikely to stop at $300,000.

Morgane Halimi, the house’s head of handbags and fashion, put the appeal in terms of language, saying fashion can be a language when words fail or are simply not enough, and that Diana understood that instinctively.

The dress has not been idle in the meantime

Its half-life in popular culture has been unusually long for a garment that was worn once. The outfit and its moment have been memorialised in clothing lines, across social media and on television, including Netflix’s The Crown. There was also a strange secondary market moment in 2024, when the television reproduction made for The Crown, which appeared on screen for about 13 seconds after a month of work by Amy Roberts’s costume team, was sold at Bonhams among 473 items from the show.

Even the car has been drawn into it. In May 2026 the Daily Telegraph reported that a Jaguar used by Diana around the time of her appearance in the dress had been put up for auction, with estimates suggesting it could sell for around £100,000.

If you want to see it before it goes

The exhibition is at Sotheby’s London on New Bond Street and runs to 24 September, so Today is the final day. After that the nearest it comes to a British viewer is a photograph, because the next stops are Hong Kong, Geneva and then New York ahead of the 9 December sale.

Whoever buys it will be buying a dress that was worn for about 3 hours in 1994 and has been discussed for 32 years since.
