Growing up in the theatrical world, Emma Watson has used her style to express characters. For ten years, she was Hermione, described in the Harry Potter books as having frizzy hair, so Watson had to keep long, curly locks. During that time, Watson grew close with the head of Harry Potter's makeup department, Amanda Knight. Though Watson couldn't change her hair, she was given opportunities to experiment with makeup. "Every now and then Amanda would let me do the extras' face paint for the Quidditch matches," she told Vogue

Regarding fashion, Watson told the Mirror she was asked at one of her first premieres, "'Who are you wearing?'" She recalled, "I thought, 'That's strange, it should be WHAT are you wearing?' That was the instant I understood it was really an art and I had fun with it."

With the completion of the Harry Potter films, Watson marked a monumental moment in her career, and she could finally do something different with her style. In 2010, she debuted a pixie cut, a drastic change from her magical character's long locks. She told Vanity Fair, "It's the sexiest I've ever felt."
