Those of you who don’t think senior citizens can be cool need to get out more. Case in point: Iris Apfel (pictured), one of the world’s original fashionistas. Iris is 90, and having a career Big Moment. She’s the subject of books, documentaries, and has a jewelry line on HSN. Also, she’s in a campaign for M.A.C. cosmetics, as are Nicki Minaj and Ricky Martin. (Ricky has declared that he is not marrying his boyfriend.) Long live Lady Iris!
