I've not had Botox, no.

In my world [of fashion] there's more things that kind of affect it. There's the retailers we do business with, our own stores, my merchandising team... Everybody has opinions, and so you definitely have to filter through a lot.

I'm not big on rap, to be honest. I just don't get it. It's angry people shouting. I like a song, melodies, people singing.

The first thing I bought that was really stylish was in 1969 when I was eleven. I saved up for a black, grey and white tie-dye grandad vest. It was too big - they weren't catering for kids my age - and hung off me, but I loved it.

I try to have an open ear, but at the end, it would never change direction to where I think I should go. Because if I listened to everybody else, they're thinking about what's right now or what was the last thing - they're not thinking about what's next.

The '40s were quite austere and super glamorous.

You have to keep challenging yourself. I've always tried to do that, and I'm not saying I've always been successful. Maybe I've rewritten the same song; it's inevitable, but I've always been mindful of taking the writing somewhere else. You can't stick in your little comfort zone.
