Keira Knightley is sure to captivate all the fashionistas with her costumes in the movie “Anna Karenina” and we are already green with envy, even though we haven’t watched the movie yet. Looks like we are not the only ones ‘green’ right now, as the actress herself was spotted by mrpaparazzi.com looking like a princess in a green dress at the Arclight Theatre, LA, for the film’s premiere.

The green strapless Erdem dress donned by Knightley looked lovely against her pale, flawless skin and the actress added a casual touch by keeping her hands in the pockets. The mint green dress, with intricate and elaborate blue embroidery at the bust and the hemline, boasted an elegant train. The actress, known for her thin frame, carried off the dress with ease and looked comfortable. No surprise, as she must have had enough practice after wearing such elaborate costumes for the movie.

The 27-year-old accessorized with just a pair of tiny diamond studs and glittery rings on her fingers with black nail color. With eyeliner applied in the cat eyes style, her tresses in an up do and pink lip color, Knightley posed at the red carpet with her signature pout. Though she was accompanied by fiancé James Righton who plays keyboards for the band “Klaxons”, the couple did not pose together.

And it was not only Knightley who pouted for the cameras. Director Joe Wright was also seen posing with the actress by The Daily Mail.

Other stars that graced the red carpet were Norwegian dancer and actor Guro Schia, who looked stunning in an off-white strapless gown, Domhnall Gleeson, Alicia Vikander, Russell Brand and more.

Another star who caught our eye was actress Alex Lombard, dressed in a patterned knee-length black dress that showed off her curves.

Knightley later attended the after party with co-stars.
