Put on a trench, you're suddenly Audrey Hepburn walking along the Seine.

Fashion is like food! Some people like sushi, others think hamburgers are divine! People like different things!

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.

Ultimately, clean lines have greater longevity, which women appreciate, and to which they can add their own personality

I've always thought of accessories as the exclamation point of a woman's outfit.

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.

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!
