Emma Watson performed magic worthy of her Harry Potter character Hermione Granger at a dinner in London last night to honor Chanel artistic director Karl Lagerfeld. The 17-year-old star seemed to magically grow up in before our eyes, in classic head-to-toe Chanel and sophisticated ruby lips. We love that Emma chose such an elegant ensemble for the event, but we want to know what you think. Tell us: Do you like Emma’s chic, adult look? Or would you prefer it if she dressed more like a teen?
