because thats what the Gedolim wear so black and white is the Jewish garb for frum men
I think you are fooling yourself. Please go ask a gadol if that is “Jewish clothing.” Granted, Jews wear it, but that doesnt make it Jewish clothing. I don’t know if you remember the recent conversation dealing with Catholic school uniforms and Jewish school uniforms, but I think this falls into the same category.
As to your point about the fashion of suits – you are WRONG. Sure, more subtle things change on a suit (like the lapel style, button style etc) or the shirts (white on white shirts used to be in style for frum men, now its plain if I understand correctly). And most of these changes ARE based on the general fashion world.
but why cant you respect a yid who wants to dress like a yid everyday, rain or shine.
I absolutely do. So every time I see a Jew wearing a kippah or see his tzitzit out, I respect him. I don’t respect someone for wearing a uniform, especially one that means nothing. It doesnt say that he is more observant or trying harder. It says he is following the fashion of where he lives.
