Diane von Furstenberg believes "less is more" with make-up.

The iconic fashion designer - who turned 65 on December 31, 2011 - thinks it is important to be sparing with facial cover ups as you get older, and she specifically believes in accentuating cheekbones: "As I get older, I've found that less is more when it comes to make up. My signature look has always been about emphasizing my cheekbones and I love Nars Multiple Bronzer. It's a great way of giving your face a mini-lift without the surgery."

Now, Diane - who has her surname thanks to her marriage to Prince Egon of Furstenberg, with whom she split in 1972 - keeps youthful with regular exercise and a healthy diet. "Although I think it's important to maintain yourself, it should be without too much labor. I love hiking and when I'm at the office I make sure I always take the stairs, even with heels on. I haven't always been an angel but I've never gone too crazy either. I live pretty cleanly, enjoy a glass of red wine every now and again. The food you eat is super-important - an unhealthy lifestyle will always catch up with you," she told Marie Claire.
