Diane is just as dynamic when it comes to her hair as she is with the roles she takes. In the past couple months, she's had oodles of offbeat bobby pins, and worn her hair up, down, and in every pretty variation in between. She even started the hot fishtail braid trend back in May. In the last couple of days, she's worn both these soft, romantic mermaid waves and this modern, minimalist messy bun. She looks great in both, but which style do you think suits her best?
