Princess Diana’s black silk cocktail dress—often dubbed the “revenge dress”—is set to go up for auction later this year, with estimates suggesting it could sell for six figures. Multiple outlets report an expected sale price around £220,000, while one source puts the broader estimate between £110,000 and £220,000.

Before the auction, the dress is planned to be displayed publicly in several locations, including London and three other cities, allowing people to view it before bidding. The Financial Post notes that Sotheby’s handled a prior sale in 1997, and the current auction is also linked to Sotheby’s, without disclosing details of that earlier transaction.

International coverage also places the auction in New York. The New York Times reports Sotheby’s expects the dress to fetch up to $300,000, reflecting how different outlets express the estimate in local currencies. While all accounts agree on the dress’s identity, they differ on the specific range and the number of viewing stops mentioned.
