'Carol' actress Rooney Mara showed up to the Oscars red carpet on Sunday night in a stunning Givenchy Haute Couture gown with diamond cutout. However, everyone seemed to be entranced by her hair which looked like it channeled The Force. The actress' three-bun hairdo perfectly mimicked Daisy Ridley's galaxy warrior look from Star Wars: The Force Awakens. While this knotted hairstyle is probably effective for fighting off the dark side, it also looked beautifully elegant on the red carpet.
