The trick is to find the style that is right for you. When it comes to trying new clothes, my advice is not to take it too seriously - it's all about having fun.

At sixteen, I was a funny, skinny little thing, all eyelashes and legs. And then, suddenly people told me it was gorgeous. I thought they had gone mad.

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

Tailored jackets with jeans is a great look for all ages. Dress up with a heel and pretty shirt, or just wear a smart T-shirt under the jacket.

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 don't understand people getting depressed about getting older. There is nothing you can do about it, so you might as well embrace it.
