The Boston Red Sox abandoned outdated, nonsensical flannel uniforms during the 1972 season. They began wearing athletic wear, pullover jerseys and beltless, "sansabelt" baseball pants that season. Red Sox Hall of Famer Carl Yastrzemski modeled a prototype uniform and stood next to Tommy Harper to demonstrate the differences in a modern baseball uniform and one that belonged in the 19th century. In my opinion, Yastrzemski's prototype Red Sox uniform is far superior to the one they eventually wore through the 1978 season. The prototype had nice trim along the sleeves, the stripes on the elastic waistband were different and there was stripes along the side of the pants too. A real Boston Red Sox Ultimate Baseball Look that never was unfortunately. I just wish there was a color version of this photograph.
