I try to concentrate on quality clothing and accessories that are worth having, and to get my people to take fewer trips by air and stay longer each time they travel. It’s more human, especially if they take time to visit an art gallery while there.

Buy less, choose well, make it last. Quality rather than quantity: That is true sustainability. If people only bought beautiful things rather than rubbish, we wouldn't have climate change!

When I'm in the street, the only people I notice are usually at least 70 years old, because they look really stylish.

Fashion is very important. It is life-enhancing and, like everything that gives pleasure, it is worth doing well.

I was so upset with what was going on in the world. I just couldn't stand the idea of being people tortured and that we even had such a thing as war. I hated the older generation, who had not done anything about it. Punk was a call-to-arms for me.

The age in which we live, this non-stop distraction, is making it more impossible for the young generation to ever have the curiosity or discipline... because you need to be alone to find out anything.

I very rarely watch my own fashion shows, but the makeup for my Fall 2011 show was just brilliant.
