If you don't need to quit drinking, you shouldn't quit drinking. I used to really love to drink, and especially living in London, it's just built for drinking.

I think that the older you get, the more you become your true, essential self. You find the things that make you happy. You whittle away the parts of yourself that mean less to you.

If you are creative, sometimes you give up a lot of things that other people have.

I love New York. It's given me so much as a designer. When I moved here, I wanted to tap into the glamour of the city immediately. More than anywhere else, New York offers itself up - you arrive and get a rush in a flash. It's dazzling. Everywhere you look, there is decoration, from a pair of jewel-encrusted shoes in the window in Bergdorf Goodman to the Chrysler Building. And New York is incredibly democratic. Everyone is packed into this tiny space. You are confronted with all manner of people, and I love that.

In another life I would love to be a cosmetic surgeon because it’s architectural. You know, you are trying to figure out where the seams go. Can I do it in one piece like Halston? Can you formaldehyde DNA?

Never, ever, ever wear anything you are uncomfortable in. Because that is what you'll project: 'I look like a fool.'

Advertising is, of course, important because advertise is the final design. It's the last layer that speaks to the customer, that tells them what you have.
