I find the whole concept of being ‘sexy’ embarrassing and confusing. If I do an interview with photographs people desperately want to change me - dye my hair blonder, pluck my eyebrows, give me a fringe. Then there’s the choice of clothes. I know everyone wants a picture of me in a mini-skirt. But that’s not me. I feel uncomfortable. I’d never go out in a mini-skirt. It’s nothing to do with protecting the Hermione image. I wouldn’t do that. Personally, I don’t actually think it’s even that sexy. What’s sexy about saying, ‘I’m here with my boobs out and a short skirt, have a look at everything I’ve got?’ My idea of sexy is that less is more. The less you reveal the more people can wonder.”
