For a mid-season 1990 game at Comiskey Park the White Sox appeared once in a uniform based on that of the 1917 White Sox.
The White Sox then switched their regular uniform style once more. In September, for the final series at Old Comiskey Park, the old English "SOX" logo (a slightly simplified version of the 1949–63 logo) was restored, and the new uniform also had the black pinstripes restored. The team's primary color changed back to black, this time with silver trim. The team also introduced a new flying sock logo which appeared as a sleeve patch on the away and alternate uniforms until 2011 when the patch was switched with the primary logo on the away uniform. With minor modifications (i.e., occasionally wearing vests, black game jerseys) the White Sox have used this style ever since.
During the 2012 and 2013 seasons, the White Sox wore their throwback uniforms at home every Sunday, starting with the 1972 red-pinstriped throwback jerseys worn during the 2012 season, followed by the 1981–86 uniforms the next season. In the 2014 season, the "Winning Ugly" throwbacks were promoted to full-time alternate status, and is now worn at home on select dates. In one game during the 2014 season, the White Sox paired their throwbacks with a cap featuring the batter logo instead of the wordmark "SOX"; this is currently their batting practice cap prior to games in the throwback uniforms.
