american; if you go to a chasidishe chasuna, you will know right away who the choshuve people are; it may not be as clear as it is in the litvishe world (i.e., kapotes) but you can tell if you’re paying attention.
Emphasizing dress to the extent that chasidim today do is a complicated, delicate subject. I don’t pretend to be an expert, but they are basing themselves on a mesorah. What to do when someone is not receptive to that mesorah….is something that they need to fix in-house. they don’t need me telling them what to do.
