Co-stars and friends Keira Knightley and Sienna Miller walked the red carpet together recently at the 2008 British Independent Film Awards. Sienna Miller wore a Louis Vuitton Spring/Summer 2009 black embellished mini-dress (which incorporated the backless trend by way of an open back) and Christian Louboutin heels. Keira Knightley’s Balenciaga dress was a tad more demure, despite the sheer trend elements.
