The Twilight Saga

1. FASHION: Monaghan kept Bella [Kristen Stewart] in "practical" pieces from Band of Outsiders, J Brand and tons of sneakers from Nike, Keds and Converse, a brand that Stewart often wears in real life.
2. BEAUTY: McIntyre maintained Stewart's rich brown hair color with Kerastase Bain Miroir Shampoo and Conditioner for Color-Treated Hair. "She goes through different stages in the movie—a breakup, her depression and then new motivation in her life," says McIntyre. "I used Kerastase Nutri-Sculpt Mousse when she was more carefree because it worked with the natural waves in her hair and gave it movement."
