Because who says the elderly can't be beautiful? Considered the world's oldest working model, Carmen appeared on the cover of Harper's BazaarThailand aged 83. She first appeared on the cover of Vogue at the age of 15, and has been working ever since, with a short stint of retirement after her second marriage in 1958. Now, you can see her in campaigns for Target and Rolex, and the senior model shows absolutely no signs of stopping any time soon.
