The most lovable aspect of Emma Watson is also her most disarming. Not her increasingly thoughtful portrayal of Hermione Granger in the Harry Potter films or her enchanting transformation from on-screen school girl to offscreen pixie gamine, but how charming she is for such a young woman of such magnificent stardom.

She wears this silver, sequined, one-shoulder Balmain cocktail dress for a taping of "The Late Show with David Letterman" so beautifully and with much more grace and elegance than most starlets her age could pull off. I think this sophistication is what the fashion industry has embraced so whole-heartedly in the months since Watson's release from the Potter franchise.

After the jump, a video in which the 21-year-old further distances herself from the hard-partying Hollywood pack by bashfully admitting she has once been drunk in her life.
