She's never been one to shy away from nud!ty.

But as Keira Knightley mingled with VIPs at a prestigious awards lunch, it was the n@ked ladies printed on her blouse that were causing a stir rather than the actress herself.

The star, who usually plays it a little more strait-laced, certainly pushed the fashion boundaries in the ensemble.

Drawings of nude women were emblazoned all over her Keira's mocha-coloured blouse, with red collar, while she had puppies printed on her A-line black skirt.

The 24-year-old actress showed off the bizarre outfit as she arrived at the Haymarket Hotel in London this afternoon.

She was a guest at the Laurence Olivier Awards Nominee Luncheon Party ahead of the ceremony which takes place on March 21 at the Grosvenor House Hotel.
