Are you blonde? Perhaps your height is 6'2"? And maybe you have won several tennis games, including Wimbledon? If you answered yes to all of these, you are Maria Sharapova. In which case I don't need to tell you about the Maria Sharapova Sunglass Collection, because you would already know.
As for the rest of you, the Maria Sharapova Sunglass Collection for TAG Heuer Eyewear features some seriously awesome shades, from aviators to large-framed, Hollywood-style glasses. No doubt you will look cool in them, but they might not help your backhand.
