Honestly, Kate Mara sort of snuck up on us. Just a few years ago, she was Rooney Mara's little sister, but now she's broken out as a beauty star of her own. Kate's best beauty looks are kind of sneaky, too. Every time she hits the red carpet, the actress wows the crowd with her sleek updos, but then she turns around and BAM! All her hairstyles are glamorous in the front and party in the back. Kate's also locked down the surfer-girl beach wave, and we're beyond jealous. There's no way we could pull off that much gel!
