Modeling can be a bit brain damaging. Starting my own brand was what I needed to do. I only model if there are such good jobs that you don't want to say no to. All that dressing up makes me say, 'What do I want to wear?' and, 'What do I want to do with Topshop?' It all kind of leads into the other things.

All of a sudden I was living what is perceived to be the model life. It was just full-on, 24 hours a day. It was work all the time. And there's always a party to go to.

I'm not really a fashion designer. I just love clothes. I've never been to design school. I can't sketch. I can't cut patterns and things. I can shorten things. I can make a dress out of a scarf.

My daughter, Lila, is my style critic. She'll say, "No, Mummy, you can't wear that." She's very good. I do trust her instinct.

I think fashion in motion is going to happen. I think that's the way things are going, but there are people who will still want to see a picture and to be able to hold it.

There was a point when it all really took off and got quite overwhelming, even though I didn't realize it.

I always have this fear that one day you are going to discover that I'm not as great as you once thought I was. Nothing feels as good as skinny feels.
