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.

Adapted from the best-selling Ian McEwan novel of the same name, ‘Atonement’ is a romantic epic starring Keira Knightley and James McAvoy as two lovers separated by circumstance and war. (With Inputs from ANI)
