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.

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.

Fluted sleeves or any sleeve that flares out before coming in again at the wrist are very feminine and a great way to distract from the dreaded 'bingo wings.'

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've had albums out since the 1970s. I was in a musical, 'The Boy Friend,' directed by Ken Russell, and I was on Broadway in 'My One And Only' with Tommy Tune, so I've always been a singer, but I suppose people think of my modelling more.

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

The 40s onwards are when we can really begin to enjoy ourselves. For many women, this is when everything comes together, and they look better than ever. The great thing about getting older is you don't have to do/wear/say anything you don't want to. It wasn't until my very late 30s that I stopped worrying about what other people thought.
