Keira_Knightley_20s_Marcel_waves.jpgKeira Knightley attended the premiere of her new movie A Dangerous Method at The Mayfair Hotel yesterday, and gave this summer's 20s trend a kick start by styling her hair in Marcel waves.

The actress - who was seen leaving the event with her boyfriend James Righton of the Klaxons, a relationship that for some reason still surprises and confuses me - sported the 1920's inspired hairstyle pulled into a bun at the nape of her neck, and paired it with some beautifully done smokey eyes, fluttery, full lashes and creamy pink lips.
