Rachel McAdams made a sweeping red-carpet entrance last night at the Sherlock Holmes premiere in LA. Opting for maximum elegance, the actress wore a metallic silver long-sleeved gown by Marchesa paired with equally stunning Christian Louboutin jeweled booties and simple Jacqueline Nerguizian jewelry. We love the dramatic draped detailing on the back of her dress and her perfectly knotted updo. Check out the slideshow to see her drop-dead gorgeous ensemble from all angles.
