It's really never fair to judge people because none of us know what's going on inside anyone else's head.

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.

Perfection is almost an illness with me, but sometimes I have moments where everything is absolutely clear and you can feel, rather than think.

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.

Style. People talk about it being stylish and beautiful, that's at the service of the story. Style for me means nothing without substance and there are moments and things about the film that are stylish but hopefully at the service of the story.

I am a perfectionist. This job is a total ego thing in a way. To be a designer and say, 'This is the way they should dress; this is the way their homes should look; this is the way the world should be.' But then, that's the goal: world domination through style.

What works with your skin and eyes? Use that to zero in on your wardrobe.
