Olivia Wilde hit Tokyo last weekend to promote her new film  Tron Legacy with a presentation. The actress, who we usually see sporting loose, messy updos or tumbling waves, was showing off a new hair look. She was wearing an incredibly tight, top-of-the-head bun. I think this is a very trendy, Tokyo look and Tron is pure science fiction, making this a brave but brilliant look. I also think she manages to pull it off more than most people could ever hope to. What do you think?
