There's no need to dress like everyone else. It's much more fun to create your own look.

I was very, very underdeveloped for my age, I hated what I looked like, so I thought everyone had gone stark raving mad.

Being young isn't about age, it's about being a free spirit. You can meet someone of 20 who's boring and old, or you can meet someone of 70 who's youthful and exciting. I met Fred Astaire when he was 72 and I was 21, and I fell in love with him. He certainly was a free spirit.

I want to continue to try and break the barrier between male and female.

Wearing a bold print gets harder as you get older. Its safer to stick to subtle prints or block colours. I have always found prints quite tricky. My daughter Carly, who is on the design team at Stella McCartney, is obsessed with them.

I ate like a horse when I was younger, and not very sensibly, though no one ever believes that.

Fashion should be stylish and fun.
