My elder sister used to get the fashion magazines, and I would go through them and find things I liked and buy fabric and copy them. But I hated what I looked like. I mean, I was sooo skinny.

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.

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.

The way I looked when I started modelling - I was a skinny schoolgirl, stuffing tissues into my little 32A bra. I wasn't trying to be that thin; I was perfectly healthy, but still - that look is a total impossibility for women over the age of 20. Fashion has a lot to answer for, doesn't it?

Even before I was discovered in 1966, I used to make my own clothes. I learned how to sew early on, and it's still my passion now. I constantly have ideas in my head about clothes so jumped at the chance to do my own collection and am very hands-on. Everything I design, I wear and I love.

What you wear for work should be comfortable and empowering. If you're working in business, your outfit should mean business. If I go to meet somebody about an acting job, or something creative, then I'll be in my jeans. For me, overdressing is my biggest fear.

Ballet pumps are the dream shoes because they are so comfortable. They look great both with jeans and summer dresses; and you can even wear the right pair with an evening gown.

My relationship with M&S continues to be an exciting journey, from modelling to designing my online range.

From as far back as I can remember, I was always insecure about my looks, whether it was my flat chest, my skinny legs, or how to cope with my body as it changed. With hindsight, I can see I was different. I was given a body that worked for photographic modelling and a photogenic face.

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.
