I used to look back at pictures and cringe but actually I'm quite proud that I've had fun with fashion and don't always look perfect. The only regret I have is when I look at something I wore when I was very young and it obviously looks like it belonged to someone else.
I've never understood having crushes on people who you don't know in real life.
Dan Radcliffe and Rupert Grint to me are like a pair of warm-hearted brothers.
I think when I was younger I wasn't really sure if I wanted to act, so I played around with a few different ideas. I wasn't sure whether I might want to write or whether I might want to do something in fashion.
I guess what really forms you as a person is what you do within your family to receive love or attention. In my family, what you had to do to receive attention was to have good conversation at the dinner table or for me to do well at school, and those were really my focuses because that was what was valued the most.
I feel like a voodoo doll. It's grim. It's gross.
I have collections of quirky things from places I've been to, like a set of Russian dolls.
If I went to somewhere busy, I wouldn't last very long. I can't go to a museum - I'll last 10 or 15 minutes in a museum. The problem is that when one person asks for a photograph, then someone sees a flash goes off, then everyone else sort of... it's sort of like a domino effect.
I find the whole concept of being 'sexy' embarrassing and confusing. If I do a photo-shoot, 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've always been fascinated by Elizabeth Taylor, and I had read that her first kiss happened on a film set, which actually made me a little sad. You need to have normal experiences of your own.
Yes, I will put it out there - I will work for anyone for free if they're prepared to make their clothing Fair Trade and organic. It's really hard to get people interested in it.
It sounds so geeky, but I really do like studying and reading, and if I'm not working on 'Harry Potter,' then my greatest relaxation is to sit with a book.
I don't want other people to decide who I am. I want to decide that for myself. I want to avoid becoming too styled and too 'done' and too generic. You see people as they go through their career, and they just become more and more like everyone else.
I want to avoid becoming too styled, too 'done' and too generic. You see people as they go through their career, and they just become more and more like everyone else. They start out with something individual about them, but it gets lost.
I like men with quick wit, good conversation and a great sense of humour. I love banter. I want a man to like me for me - I want him to be authentic.
Hermione uses all these big long tongue twister words. I don't know what she's going on about half the time!
I'm a very heady person; I'm in my head a lot.
I'm a real Londoner. We have very grey weather in London, and I think it encourages a very eclectic and crazy fashion sense. I mix high-street stuff with more high-end fashion, and I love vintage.
It's almost like the better I do, the more my feeling of inadequacy actually increases, because I'm just going, 'Any moment, someone's going to find out I'm a total fraud, and that I don't deserve any of what I've achieved. I can't possibly live up to what everyone thinks I am and what everyone's expectations of me are.'
In terms of men I fancy, I think the actor James Franco is gorgeous. But I find it odd to be described as a sex symbol myself.
