To get the thread back on track, if I may…
The “Chabad Look” to which I was referring I believe might actually be b’shittah. Chassidim usually have more established dress-codes than the rest of us. A big part of Chabad’s philosophy is that the Baal Shem Tov was extending frumkeit to the less financially fortunate; the assertion being that the Yeshivish velt had become too reserved for the rich. I think that shittah continues to influence their hanhagos today in that they might take pride in worrying less about looking primp and proper than their Litvish counterparts.
While Litvaks are very delicate about our hats and will replace them if they go limp, the Lubavitcher Rebbe wore a more tattered-looking hat that any of his chassidim could afford. The Rebbe didn’t dress royally like other chassidishe rebbeim. And, Chabadniks may keep strictly to a button-down + black jacket dress code, but they aren’t always tucked in and worried about their hats looking perfect. I think it’s all part of finding a balance between showing that a yid dresses respectfully, while also showing that yiddishkeit is not reserved for the posh.
Any Lubavitchers here want to back me up, or am I missing the mark?
