 Keira Knightley’s Famous Green Atonement

Dress Set for London Auction in December 2026

LONDON, United Kingdom — One of the most recognisable costumes in modern film history is preparing to return to the spotlight as the famous emerald-green dress worn by British actress Keira Knightley in the 2007 romantic drama Atonement is set to be auctioned in London.

The elegant silk gown, designed by award-winning costume designer Jacqueline Durran, will be offered at Christie's on December 9, 2026, as part of an auction titled Love & Lust: A Literary Guide.

Christie's estimates that the dress could sell for between £100,000 and £120,000, reflecting its lasting popularity among film fans, fashion enthusiasts and collectors.

Nearly 20 years after the film introduced the outfit to international audiences, the upcoming auction offers collectors an opportunity to own an important piece of contemporary cinema history.

The Story Behind the Famous Emerald Dress

Knightley wore the gown while portraying Cecilia Tallis in Atonement, a film directed by Joe Wright and adapted from Ian McEwan's novel.

The story follows Cecilia and Robbie Turner, played by James McAvoy, whose relationship is affected by misunderstanding, jealousy and the consequences of a false accusation.

The green dress appears during one of the film's most memorable romantic sequences, helping establish the visual identity of the character and the emotional atmosphere of the scene.

Its distinctive colour, flowing silhouette and backless design helped make it one of the film's most discussed costume choices.

How Jacqueline Durran Developed the Design

Creating the gown required careful consideration of the film's setting, characters and visual style.

Director Joe Wright wanted a striking green outfit that would stand out on screen and move naturally as Knightley's character walked.

Costume designer Jacqueline Durran drew inspiration from fashion references of the 1920s and 1930s while developing a design that combined historical influences with a distinctive modern appearance.

The result was a lightweight silk gown with a flowing skirt and an open-back design.

The costume became particularly memorable because of the way its colour and movement complemented the film's cinematography and storytelling.

Durran later discussed the creative process behind the dress in an interview with Entertainment Weekly, published in 2017.

Why the Dress Has Remained Popular

Some film costumes become memorable because they are closely connected to important scenes and characters.

The emerald gown from Atonement is an example of how costume design can become part of a film's wider cultural legacy.

Rather than simply serving as clothing, the dress contributes to the atmosphere of the story and helps audiences remember a particular moment in the film.

Its continued recognition among fashion and cinema enthusiasts has also made it an interesting subject for collectors.

The upcoming auction demonstrates how important costumes from successful films can retain cultural and financial interest long after their original productions have ended.

What Else Will Be Included in the Christie’s Auction?

The emerald gown will not be the only significant item offered during the Love & Lust: A Literary Guide sale.

According to Christie's, the collection will bring together books, manuscripts, artworks and other cultural objects connected to themes of romance, literature and artistic expression.

Among the highlights are original poster artworks associated with two classic films:

- Metropolis (1927), the influential science-fiction film directed by Fritz Lang.

- Dracula (1931), the classic horror film based on Bram Stoker's famous novel.

The sale will also feature handwritten letters from British naval figure Horatio Nelson to Emma, Lady Hamilton.

Another notable item is an original costume worn by celebrated ballerina Dame Margot Fonteyn as Princess Aurora in a 1960 production of Tchaikovsky's The Sleeping Beauty.

These objects provide a wider look at the relationship between fashion, literature, cinema and cultural history.

When and Where Will the Auction Take Place?

Christie's has scheduled the live Love & Lust: A Literary Guide auction for December 9, 2026, at 4 p.m. GMT.

The event will take place at Christie's King Street location in London.

The auction house has also announced a public exhibition running from December 4 to December 9, 2026. The exhibition will be free to visit, giving interested members of the public an opportunity to view selected items before the sale.

The emerald gown is expected to attract attention from collectors who have a particular interest in Atonement, film costumes and the history of fashion.

However, the final selling price will depend on bidding during the auction.

A Lasting Connection Between Cinema and Fashion

The planned sale highlights the important relationship between costume design and the film industry.

Costumes help establish a character's personality, reflect the period in which a story takes place and contribute to the visual identity of a production.

In some cases, a particular outfit becomes so closely associated with a film that it develops a reputation beyond the original story.

Knightley's emerald gown is one such example.

Its journey from a film production to a private collection and now to an international auction illustrates how a carefully designed costume can become a valuable cultural object.

Final Thoughts

The upcoming sale of Keira Knightley's famous green dress offers another opportunity to appreciate the creative work behind one of modern cinema's memorable fashion moments.

Designed by Jacqueline Durran for Atonement, the gown has remained a subject of interest among film and fashion enthusiasts since the movie's release in 2007.

With an estimated auction value of £100,000 to £120,000, the dress is expected to attract attention when it appears at Christie's in London on December 9, 2026.

Whether it reaches the top of its estimated price range remains to be seen, but its place in contemporary film fashion history is already well established.
