Born in London in 1928, she started working as a model in the early 1950s. Now she works for brands as diverse as Vans, Dolce & Gabbana and Olay, regularly reminding Vogue readers that old can be cool.
She's since worked all over the world, juggling bringing up three children, and not just modelling her famous chiselled cheekbones but appearing in videos and on TV too.
"People over 60 have more money than they used to have and they take more care of themselves. They want to see fashion on older people," she says.
But she has little time for how fashion is evolving. "I hate all those strapless dresses on the red carpet. It's not nice, it's not right, they might as well stand there naked! I want to look elegant."
Daphne thinks the key to a good later life is to get out and about and do things and she loves seeing friends, visiting stately homes and does all her own gardening at her Hertfordshire home. She loves painting too but she looked so striking that her drawing class kept asking her to be the model - and she finally capitulated!
10 top tips for ageing well
Here she shares some of the secrets to that ageless beauty
1) Age naturally
I've never had botox or cosmetic surgery, why should I? It's so expensive and afterwards you can't move your face. I like making faces!
2) Let the grey shine through
I haven't dyed my hair in years. I wash it once a week and keep it long, though I always wear it up. I don't go to the hairdressers much as when it gets a bit untidy I just tie it up in a ponytail and snip the ends off. I'd rather spend my money on going to the theatre.
The best make up for grey hair
3) Cleanse, tone and moisturise
I can't be bothered with expensive face creams, I've done well enough with rose water, Nivea and Boots own brands. Your skin reflects what you eat and drink. I do drink lots of water.
4) Share a meal with a friend
I love my food but I eat healthily, little and often. When I go to a restaurant I share a main course or ask for a children's portion. At home I never have anything out of a packet and eat lots of raw food.
5) Do your own housework
It;s the best exercise. I'm a bit creaky now but I also do the gardening. Plus ballet exercises in the morning and I love walking and pilates. Occasionally I even get on my old exercise bike.
6) Find the positive
You won't be beautiful if you're grumpy. We all have ups and downs. I have glaucoma, for instance,but the eye drops I use have made my lashes longer. There's always a reason to look on the bright side.
7) Be curious
It makes your brain tick and your eyes sparkle.
8) Keep exercising
I do my own version of yoga every morning, a cross between yoga and ballet. It keeps me flexible.
