My name's Katharine Hamnett. I'm a fashion designer and I've been campaigning on sustainability for the last 30 years.
In the 1980s we were on a complete roll. We did some research and I thought, 'Ah, it's gonna be fine.' Cut to the kill. Every single raw material was having a horrendous impact on the environment. People I've bought hundreds of thousands of metres of cotton from were saying, 'Why should we make it organic cotton since you're the only one asking for it?'
'Choose life' – that was our first T-shirt. 'Save the future', 'Save the bees'.
Clothing purchasing is driven by desire. You know, they've got to be desirable. They can't just be sustainable. This coat is recycled polyester. Padded silk, because I was trying to find an alternative to fur, and it actually works.
I think it's important, you know, as well as campaigning, to actually prove that it can be done.
