You don't see this very much in baseball anymore

Knee-high socks.

Alex Williams, for one, would like to see more of this in baseball.

Oh, for those days of yesteryear.  The World Series is a showcase for not only the finest teams in the game, but also, for about the 15th year running, the regrettable fashion trend of the baggy, pajama-pant look. At one point, the style may have communicated a certain rebel swagger, but now everyone from baseball purists to fashion wags is crying “foul.”

San Francisco Giants rightfielder Hunter Pence takes the old style to new heights.  There's even a Hunter Pence High Socks Facebook page, though it has just 17 "likes".

Then there's the traditional stirrup look.
