Did you ever see so much beading and so many Swarovski crystals in your life!?!  That costume must be SO heavy! The hours and hours that would have gone into all that – it could only have been done by hand. Wow…

I just read about a survey conducted in 2008, that placed Keira Knightley’s green silk gown in Atonement  as the best film costume EVER. I’m not sure that I agree with that, but I did adore that gown and have been thinking about buying a reproduction.

From the Press Association: ‘The emerald green dress worn by Keira Knightley in Atonement has been voted the best film costume of all time. The bias-cut, backless silk gown had fashion editors raving when it first appeared on screen last year.
Knightley’s character, Cecilia Tallis, wore it during a pivotal scene in Joe Wright’s period drama, which is tipped for Oscar nominations. The survey was done for Sky Movies and British InStyle. Following Knightley’s dress were:

• white dress worn by Marilyn Monroe, in The Seven Year Itch;
• little black dress worn by Audrey Hepburn, in Breakfast at Tiffany’s;
• skin-tight pants worn by Olivia Newton-John, in Grease;
• blue gown worn by Kate Winslet, in Titanic;
• tie and waistcoat combination worn by Diane Keaton, in Annie Hall;
• satin corset worn by Nicole Kidman, in Moulin Rouge;
• stockings and bowler hat worn by Liza Minnelli, in Cabaret;
• gown worn by Cate Blanchett, in Elizabeth;
• dresses worn by Vivien Leigh, in Gone with the Wind.

Ian Lewis, director of Sky Movies, said, ‘There’s no doubt that Keira Knightley’s dress in Atonement created a massive stir this year, so it will be interesting to see whether it attains this stand-along iconic status in years to come.”
