Diane von Furstenberg continues her reign on the Powerful Women list, after ranking No. 33 last year. Her collections are sold in more than 55 countries, and her dresses can be seen on the red carpet and on the first lady. She's currently serving her fourth term as president of the Council of Fashion Designers of America, and is always one step ahead. Case in point: she dressed her models in Google Glasses at her Spring '13 fashion show.
