Back in the '60s, there was a car sticker that read, 'Forget Oxfam, Feed Twiggy,' but I ate like a horse.

I’m just mad for San Francisco. It is like London and Paris stacked on top of each other.

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 eat healthily because that's the way I prefer to eat, and I'm sure it helps keep the weight off.

For me, getting older doesnt mean throwing away a favourite-coloured lipstick or a fabulous pair of boots; instead, its about harnessing all the great things I have learnt over the years about what does and doesnt suit me, and enjoying the way in which cleverly selected outfits can enhance the nice bits.

We want to raise the children the parents aren't raising. I think we want to press individuality on people, though that doesn't necessarily mean being like us. But, it doesn't mean that if you come dressed like us that you aren't being yourself.

If I want to calm down, I'll buy some fabric, get a pattern, shut myself in a room and stay there for days, really happy. And at the end of it, you get a bedspread or some curtains or something to wear - it's lovely.
