It’s red carpet season and stars are putting on their party dresses. Cecilia Dean looks amazing, as always, in white Givenchy while Rachel McAdams took some flack for her side boob-flaunting Suno but we kinda dug it. Carey Mulligan and Michelle Williams looked prim and party-perfect in ’50s silhouettes by Prada and Wren. And Cameron Diaz just sizzled in fire-engine red.
