“Let’s pose it the correct way. A white shirt and dark pants worn as intended or the torn tight jeans(sold that way) worn as intended.”
Surely you are aware that jeans are sold in many other styles. Tight and/or torn are not the only jeans sold in stores. One can purchase black cotton pants that are tighter than the jeans you dont like, does this move black cotton pants down on your bakovidik scale?
While you are free to disagree, I dont think many people will assert that the yeshiva “uniform” has to do with bakovidik as much as it does uniformity which in turn answers the question of the OP. When part of the herd, one follows the herd (this is not a statement of right or wrong).
