For a charity event in London, fashion heavy-hitter Sienna Miller rocked a daring, disheveled, rocker-chic style that had fabulous written all over it. Never one to shy away from taking a fashion risk, Sienna showed a bit of skin wearing a sequined vest as a top under a studded Temperley London blazer paired with faded low-rise jeans. She kept on with the rocker motif in the footwear department with a pair of Alejandro Ingelmo metallic woven slingbacks and completed her fierce look with a sleek black Romanek clutch. Each piece in this amazing look is simply to-die-for and can create countless killer ensembles. Check out my slideshow to get the look!
