I can sketch up a storm, and I'm very involved in how clothes are constructed, but I have a short attention span.

It's funny when I hear people complain - particularly about the most fabulous parts of being a designer, like when you're getting ready to work on a show. I don't even know that I'm tired. I could stay up for six days straight! No drugs, no coffee, no nothing. I'm just so excited.

Every woman should own a shirtdress

I think the older I get, the more I realize that the ultimate luxury is time.

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 feel unbelievably fortunate. How many people get to do what they always wanted to do and do well with it and continue to be surprised and see amazing places and meet amazing people?

Because of what's going on with the economy, I think women are realizing that maybe they don't need a closet full of clothes. They just need the right clothes.
