Who says the models at New York Fashion Week have to be young? Carmen Dell’Orefice, 81, surprised attendees this year with two runway appearances Sunday, ABC News reports. Dell’Orefice, known as the oldest working model in the world, started modeling in the 1940s and was on Vogue's cover when she was just 15. On Sunday, she first modeled a Norisol Ferrari gown, then later a Marimekko design. (More Carmen Dell’Orefice stories.)
