My "signature" fashion is not really all that "signature". The only thing I can think of for me right now is the backwards turned baseball hat and I have to wear the normal length of socks or longer, the short ankle socks are killing me LOL. Donald Young has his sideways-tugged baseball hat. Rafael Nadal has the clam-diggers. Anna Kournikova was one of the original founders of the short skirts, sleeveless tops, and tight dresses. Agassi had the spandex, mullet combo. The Williams sisters took fashion to a new level and continue to. Stan Smith had the "tennis whites" look, Bjorn Borg with the headband, etc. did his thing, What is your "signature" fashion?
