I’m waiting for a Chassidic Machon for Textile Research where clothes are crafted in a way to provide a cooling experience, like an ice vest and thereby preserve the look, but not the feel, of the mandated uniform.
As time goes by, and we over-focus on form, content seems to suffer. When I was a boy, R’ Zalman Serebryanski ז’ל used to wear a mid-grey Kapoteh. Yes, it wasn’t black. His hat had a very short upturned brim. But then, again, he was a Chassid in content and seemingly less troubled by form.
It’s interesting to note that during the weekdays, other Chassidim, such as Ger, often don a standard fedora. Unless I’m mistaken, in the days of yore, they wore a Poilishe Hittel-one of those Donny Osmond style caps. I’m also skeptical whether the standard Chosid always wore a white shirt during the week. Did they?
Curiously, the Sefardim (at least those of them that don’t try to emulate Ashkenazim) didn’t have a dress code that required them to either all dress the same, or wear something akin to the Chacham.
And finally, we did change our names, clothes and language after we left Mitzrayim. Maybe that’s the answer: let’s go back to what Moshe Rabbenu wore?
