In my opinion one of Mirka's greatest influences in Fed's career is the way she transformed his outward appearance. Fed used to be scruffy, unshaven, with baggy clothing and a ponytail. She made his outward appearance match the elegance of his game. This made him so much more marketable and has made him wealthy beyond his imagination. I love his Rolex commercials where they show slow motion of his wonderful groundstrokes when he is dressed in a well-fitting jacket and slacks with great hair. He looks like a prince. When I see video of old scruffy ponytail Fed I always laugh out loud.
