Just when she was starting to become a tad predictable, Keira Knightley switched things up at the ‘Anna Karenina’ LA premiere held at the ArcLight Hollywood in California yesterday evening.

I was starting to tire of the samey Valentino gowns, so thank heavens Erdem Moralioglu created this custom gown for the British actress, which was inspired by his Spring 2013 collection.

The mint duchess-satin strapless gown features the same blue lace embroidery we saw on the runway.

That punchy pink lip is to die for. She really wanted to mix things up on this occasion.

A pinned updo and star diamond-encrusted Chanel earrings completed her look.
