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.

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.

The biggest lesson that I've learned is that fashion is this tightrope where you have to be consistent but inconsistent. You need the connective thread but at the same time you need a sense of surprise.

The greenest thing you could do in fashion, is to buy something great that you’re going to use for years

When I was a kid, I was trendier. I'd wear anything. I was in love beads and platforms...

Great style means having a point of view, but evolving your look is even more important. Rushing to embrace every trend will leave you fashionable, but not stylish

Women are much more comfortable making their own style rules now. They want pieces that will make their busy lives easier.
