Our economic system, run for profit and waste and based primarily on the extractive industries, is the cause of climate change. We have wasted the earth's treasure and we can no longer exploit it cheaply.

We have got to change our ethics and our financial system and our whole way of understanding the world. It has to be a world in which people live rather than die; a sustainable world. It could be great.

The thing that makes my clothes really different is that, number one, they are really great designs; they're not tacky; they are very professional; the design is made from lots of decisions.

I just use fashion as an excuse to talk about politics. Because I'm a fashion designer, it gives me a voice, which is really good.

Home, more than anything, means warmth and bed.

I don't care if you get up in the morning and don't wash, don't put any make-up on, don't do your hair, even, but you have to have clothes if you want to look different.

I have been asked what would I ban immediately if I could. Advertising.
