“as Yidden are supposed to have a uniform”
Please cite sources for this requirement.
A uniform requirement is far more than just dressing in a manner that those who see you will know that you are Jewish.
A uniform is very much associated with the military where a rigid structure is needed to be able to conduct war. In an army there is no room for individual creativity.
Even in wartime, not all functions need the uniform. Those building the weapons do not.
The pre-WW2 litvishe yeshivos did not have a uniform. Lakewood when Rav Aaron Kotler was alive did not have the white shirt and black hat uniform.
But now, every boy turning Bar Mitzvah is presumed to be “military academy” material and must wear the full uniform.
