Sienna Miller's Bob Is Amazing

You can do messy hair for formal events — just ask Sienna Miller. Miller attended the London Evening Standard Awards on Monday night, and as stunning at her dress was, I mean, how can you ignore that hair?

The actress and her fiancee, Tom Sturridge, (who looked pretty dapper himself, I might add) walked the red carpet together at the 60th annual London award show, and it's safe to say, they were probably the best-dressed couple in attendance. Miller and Sturridge wore Burberry, to be quintessentially British about it, and his debonair fedora was the perfect accompaniment to the blonde beauty's elegant gown. Sienna's rose and silver dress practically dazzled, but the elegance stopped there. The bohemian starlet kept her new bob tousled and wavy, with a deep side part and strands falling in her face. Her messy, undone locks kept the overall look from being too polished, and, let's be honest, polished is the last thing Sienna Miller wants to be. Given the formal nature of the event, her hair might be slightly out of place, but with a sleek gown and minimal make-up, Sienna shows just how you can transition messy hair into evening. And it's everything.
