While Madonna and Rihanna duked it out for the sartorial spotlight at last night’s Grammys, Hollywood A-listers gathered across the pond for the 2015 British Academy Film Awards. While the London red carpet may have lacked butt-flashing, stars still brought it, including Julianne Moore — who showed up in a tasteful red Tom Ford, and took home the award for Best Actress in a Leading Role for her performance in Still Alice. Meanwhile, Amy Adams showed up in a sleek white Lanvin gown, Reese Witherspoon opted for Stella McCartney in deep purple, and Keira Knightley further explored her current interest in unusual textures, and choose a ruffly gown by Giambattista Valli.
