Twiggy

I'm grateful for my lines of wisdom. Of course, there are days when I think: 'Oh my gawd, I look a bit tired.' But I can pull it together if I have to.

I am very sad that some designers are still using real fur when the fake alternatives are so effective and so easily obtainable.

Wearing a bold print gets harder as you get older. It's 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.

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.

I'd love there to be more larger models, but it's just not going to happen. Designers love to design for slim girls.

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.

Being young isn't about age, it's about being a free spirit. You can meet someone of 20 who's boring and old, or you can meet someone of 70 who's youthful and exciting. I met Fred Astaire when he was 72 and I was 21, and I fell in love with him. He certainly was a free spirit.

I don't like it when people say, 'You're 45, so you should be wearing X and never Y.' For me, dressing is about attitude, not age.
