The green goddess

Keira Knightley's Atonement dress is being auctioned at Clothes off Our Back, with proceeds going to the Children's Charity of Southern California.

The fabulous green dress was recently voted the most iconic film outfit in a recent poll by Sky Movies and InStyle (the dress seems to be very fresh in people's minds - amazingly, it beat Marilyn Monroe's dress from The Seven Year Itch, Audrey Hepburn's Givenchy gown from Breakfast at Tiffanys and Olivia Newton John's leggings from Grease).

The thirties-style gown was made by costume designer Jacqueline Durran and because the dress was so fragile, multiple copies were made for Keira to wear during filming.

The bidding for this size 2 dress stands at $6,000 this morning, with 18 days left to go before the auction closes.

Happy bidding!
