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.

I think the trick is, how do you spend time doing it but make it look like you haven't spent time doing it? Over the years you look at women like Lauren Hutton and everyone says: 'She just pulled her hair back and ran out of the door.' I've been in fittings with Lauren and she definitely thinks about it. She just knows how to make it look easy.

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.

It's an unbelievably tight race for hideous today.

In early days, I showed everything I made. There was no such thing as editing a collection. In the '80s, it got to the point where we'd have shows with a hundred looks. You'd want to order a pizza before it was over!

I can't dance and I can't sing too well.

I think a lot of women have too many mini skirts in their closets.
