You know I can't stand Keira Knightly as an actress. But my goodness me, she is slamming it from a style perspective this week. Following hot on the heels of that adorable navy Chanel dress of last week, Keira was at Sundance to premier her new movie Laggies. For the occasion she wore grey Valentino knits with a cute-as-a-button Mulberry belt. I don't think I could approve more.

Then last night she was back home in London, all togged up in a gorgeously simple Proenza Schouler black dress for the Jack Ryan premier.

The dress is deceptively simple as the slit up the front and the buttons down the back bring such life to it. And there there are those shoes. How divine?
