It's hard to believe that the first Harry Potter movie came out 10 whole years ago! Crazy! Time flies when you're making potions and playing quittage, you know? But as muggles, we've been admiring Kids' Choice nominee Emma Watson since she was 10! So it's no surprise that she looked so adorable back in the day at the premiere of Harry Potter! We doubt that this fashionista would ever leave her house wearing something like this nowadays, but we would so wear her outfit to a costume party!
