Emma Watson and her megawatt style

Let it be known that the adorable Emma Watson (she plays Harry Potter's BFF Hermione, in case you've been living under a rock), who recently made headlines when she chopped off her locks in favor of a cropped Mia Farrow-esque pixie cut, has always had style. She hit the first "Potter" premiere in faux-lizard boots and a feather boa at the age of 11. Fast-forward to the premiere of the most recent installment of the franchise, "Harry Potter and the Deathly Hallows - Part 1," and we can see the evolution of a fashion icon. No feather boa this time, but she did opt for a sexy black lace minidress with a feathered hem, by Rafael Lopez for Atelier Mayer. We spoke with the college sophomore about honing her sense of style, the importance of dressing appropriately, as Audrey Hepburn once advised, and the new line of eco-friendly clothing she's launching with Alberta Ferretti.
