There are plenty of reasons to be intrigued by Gone Girl star Rosamund Pike (read her recent Glamour cover interview for more than a few), not the least of which is her hair. There's the fact that her bob is shaved in the back—for some reason, we wouldn't expect her to be rocking the undercut trend. And there's her knack for dressing her short hair up in intriguing new ways. Here are two examples from her weekend at the Palm Springs International Film Festival. 1. On Saturday, she proved that elegant updos can happen on short hair, sweeping hers into the sleekest modern French twist. It's so perfect it's like a sculpture! The front featured a simple, clean side part. 2. On Sunday, she showed how cool a teeny-tiny ponytail can look, with her buzzed lower section adding the vibe of a half-up hairstyle. How do you like these short-hair styling ideas we spotted on Rosamund Pike? Would you love to try either of them on your own hair sometime soon?
