Keira Knightley’s ‘Atonement’ dress could fetch $166k at auction — but New Yorkers can see it for free

Christie’s has announced the sale of Keira Knightley’s emerald dress from the 2007 film *Atonement*, with an estimate of $130,000 to $160,000. The gown will be on public display at Christie’s Rockefeller Center galleries in New York until 17 November, giving visitors a chance to see the film costume for free before the auction.

Designed by Jacqueline Durran, the silk dress previously sold for $35,000 in 2008, equivalent to about $55,000 today after inflation. Christie’s says it will be auctioned on 9 December; the design has inspired later fashion, including work by Alexa Chung and Tory Burch, while the article also points to lower-priced green dress alternatives.
