We've discussed Whitney Port's hair at length and we even know the exact science to her gorgeous colour, but it's rare that she treats us to anything but long, loose locks. No complaints here—I'd be prone to showing it in all its glory if it was my mane, too. But late last week she displayed a different style at the Annual New Yorkers for Children Spring Gala: a Danish-style top bun, complete with face-framing tendrils. The day after it was back to her signature style. Which look do you prefer?
