I think this is the first time I have ever had a girl crush on Sienna Miller.

I’ve always seen her as a Kate Moss clone or a serial husband stealer, but for once it’s her style that I’m focusing on because she continues to give us something fresh and new each time she takes to the red carpet.

On Friday she attended a special screening of “G.I. Joe: The Rise of Cobra” at Andrews Air Force Base in Camp Springs, Maryland with her cast mates.

Opting out of wearing army fatigue the actress wore a beautiful Isabel Marant Fall 2009 printed dress with a ruched bodice and 3/4 length sleeves.

Her dress was paired with some lusty worthy booties from the same collection and a collection of platinum bangles.

Her hair was uncharacteristically blown out and she opted for a pop of red on her lips.

This is my favourite look so far on this promotional tour.

“G.I. Joe: The Rise of Cobra” opens in the US and UK this Friday, August 7.
