This is a pair of 1975 Chicago White Sox home pants worn by Jorge Orta. The pants are size 32 Wilson pants, 23" inseam, with the year '75 and Set 3 in the waist. The pants are stained and there are two patches, one at the bottom of the left leg and another on the back of the left leg.
Comes with a red belt, although it has the number 31 marked on it. May have come from another player, but it's the same belt worn with the uniform.
