Being a grown-up woman doesn't mean you can't look beautiful, individual and different.

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.

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.

If you just say nothing, there is no way they can make you talk.

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

I used to do my own make-up. I used to have this doll that had those big eyelashes on the top and bottom, and I think I copied her when I was doing my eyes, putting false eyelashes on the bottom as well as the top. So I came up with that look myself.

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