When Diana stepped out of the car at the Serpentine Gallery in 1994, all eyes were on her black strapless silk gown. The dress, designed by Christina Stambolian, became known as the “revenge dress” after Prince Charles publicly admitted to adultery the same day. It instantly turned a night of charity and scandal into a fashion‑flipped moment of empowerment.\
\Now Sotheby’s has announced that the gown will return to the auction block on 9 December, with a ceiling estimate of up to $300,000 (£220,000). The listing marks the first time since 1997—when the princess sold 79 of her own outfits for charity—this piece will be offered to collectors.\
The dress is more than silk; it’s a soundtrack to a pivotal hour in monarchy history. As the first front‑door outlay at the “Revenge” ball, it married sartorial bravado with public narrative, enabling Princess Diana to reclaim the story she was being told. “On her own terms, she turned this dress into one of the most powerful messages she ever made,” Sotheby’s air of talk said.\
What could the dress fetch in 2026? In the same auction season, a Jaguar XJ40, another prop from that gala, sold for £66,000, while a sweater featuring a black sheep sold for £920,000 in 2023. Should the “revenge dress” exceed expectations, it would join the ranks of high‑profile, high‑priced royal memorabilia.\
Fashion historians and royalty enthusiasts alike are glued to the event. Whether it will become a new benchmark for royal fashion pieces, or simply a stylish relic, the auction’s outcome will be watched closely.\
