Amy Adams went for a refined retro vibe in a one-shouldered black-and-white Giambattista Valli number. Tonight's red-carpet ensemble is just further proof that she's nailed that stunning balance between an old-school Veronica Lake movie star and a Disney princess á la Enchanted. While the sweeping floor-length gown spoke for itself, we have to point out her awesome gold bow-tie belt — a perfectly ladylike-cum-quirky accent that provided a gilded boost to the outfit as a whole. She finished off the look with Brian Atwood sandals, Fred Leighton jewelry, and a Judith Leiber clutch. Are you a fan?
