Emma Watson has emerged as quite the young fashion star—from wearing Rodarte and hanging with Daphne Guinness to shooting with Mario Testino for the new Burberry ads that will break in August magazines, where she looks like the picture of youthful sophistication. And with each move, we love her more and more. Now, if only we could groom our young American stars to grow up in the spotlight with as much style and grace as the girl best known as Hermione. We suppose Dakota Fanning is holding her own, but other examples elude us. Christopher Bailey said of Emma, "Her charm, intellect and brilliant sense of fun made the whole shoot feel like a picnic on the Thames." We can hardly imagine any designer saying the same of one of our teen queens.
