The Power Player today is fashion designer Betsey Johnson. She kicked it up a notch with sexy workout clothes under the brand "BJ kicks a" for Fall 2013. To put her collection to the test, she led her models in a wild workout session at her runway show at Mercedes-Benz Fashion Week in New York. The 70-year-old studied dance as a child and now practices yoga. Her clothes and accessories are not only fun, but she says they also very practical.
