Brinkley is the author of "Timeless Beauty," in which she shares her strategies for looking your best at any age. She recently spoke to the Huffington Post about how far the modeling world still has to go in terms of appreciating the wide range of beauty.

"I think that my industry has come a long way, although we're still a little too appreciative of the super, super unhealthfully skinny body," she said. "People's bodies come in every shape and size, and I really believe that all shapes and sizes should be celebrated as long as that's your natural, healthy weight."
