China is exciting because it is an extremely curious and interested market. What more can a designer ask for? The client here is bold and willing to try new things, which a country with a long fashion history wouldn't dare. France or England is weighed down by all these rules, elaborate etiquette, do's and don'ts. Things here move incredibly quickly.

The craziest thing about fashion people in general, not just designers, is that it's always, "Oh my God, you lost weight! I love your hair!" Or "Oh, you're so tan!" Or, "You're so skinny! I love your shoes!" These are fashion icebreakers. Everyone's always looking at each other.

When I'm not working I'm a slug - a full slug. I am not good at the in-between. I'm either fever-pitched or want to just pass out on a beach with a really sleazy book and eat a cheeseburger.

The minute it gets to a runway, you're tempted to do some high jinks. I don't want to show something I won't produce. I want people to wear the clothes I show.

I not only enjoy it, I think, how do you design things that are applicable to life - unless you live it?

When you try on something, you have to ask yourself, 'How many ways could I wear this? Could I wear it to work? To dinner or drinks? Will it span the seasons' If you have to think too hard about those questions, then skip it.

I love fashion because it's plugged into the zeitgeist, so it's always changing. Thirty years ago, I could never have predicted I'd be where I am today, so I know I don't know what's going to happen in the next five years or the next 20 years. I have my predictions—I'm sure technology will continue to have an impact on fashion, particularly the way people shop. I think quality will be increasingly important—we're moving away from a time of fast fashion. But really, the only constant in fashion is that you must keep moving forward, otherwise you'll be left behind.
