Washington, Sept 17: Actress Keira Knightely failed to overcome her habit of breaking important props while filming, for she recently broke two crucial items on the set of period drama ‘Atonement’.

The 22-year-old actress, who faces difficulty in keeping film props intact, broke an exclusively designed Chanel necklace and a lighter while filming ‘Atonement’.

"I was wearing a Chanel necklace and it got stuck,” Contactmusic quoted Knightely, as saying.

Keira Knightley has turned into a fashion icon due to her role in new film ‘Atonement’.

The actress’ marvellous Forties look as mysterious Cecilia Tallis has triggered a retro trend amongst fashionistas.

Lady-like fashions such as waspish waists, skirt-suit silhouettes and feminine tailoring are turning out to be the season’s hottest trends.

And it’s not just the wardrobe that's facing a transformation, for Keira’s soft 1940s curls are also making waves on the runway and red carpet.
