One thing that is exciting about fashion is the surprise element. People don't know what they want. They just know when they see it.

I think of many people and no one as a muse. I love the way Sofia looks always, and I love the way Kim looks always. Fashion may be part of their world, but it's not their whole life. It's not everything.

I love my life. I can't believe I work in New York and Paris. That I work for Louis Vuitton. That I work for Marc Jacobs. It seems really weird every time I say my full name - like, that's me, and every time I hear the receptionist say my name, it's still weird.

Young girls need to learn that sexiness isn't about being naked.

I always say I lived my life with my grandmother. She was emotionally stable, and she was very encouraging to me.

Sex is always good, isn't it? Well, actually it's not always good, but it's always a good thing.

There is a small world of people who are very interested in contemporary art and a slightly bigger world of people who look at contemporary art. But then there is a much larger world that doesn't realise how influential art is on things that they actually look at.
