OC 91:6
off the bat, it says this is derech chachamim and talmideichem .. here, the argument seems to be circular or at least aspirational: let’s all wear black hats and voil�, we are T’Ch. Could it be that some people who come to shul are not T’Ch or at least are modest enough not to consider themselves as such?
2nd, atufim – is this a hat or a turban? Or as Rava b’ R Huna in Shabbat 10 – socks ? I am all in for requiring socks in shul, by the way.
3rd, as DaMoshe mentions, everyone refers to the standard of the time of what is respectful clothing. We seem to have a machlokes here what is considered “standard of the time” – something that is respectable in the general society (not “average” rapper, but average professor or congressman, John Fetterman excluded) or should we go by the standards of the current Jewish community. Would you agree with this?
I have to note that referring to the Jewish community standard, this becomes “no true Scotsman” fashion. You simply declare that your community is the standard and, thus, everyone else is in violation of OC and are, thus, not proper community. Of course, at some point – probably 18th century, Yidden clearly adopted standard Polish dress and then (some) refused to change it. I personally think that wearing 18th century jacket was a reasonable idea when 19th century jacket represented haskala and there was a good reason to stand firm against it. I do not think, though, that we are still in the same boat, as we developed more sophisticated ways to deal with modernity. Reasonable people can disagree here, of course.
