“oomis- how does the Rabbi of your shul dress during the week? Black and white or colored shirt? We Jews are supposed to look different than the Goyim. “
When he is at work (teacher)or at Shul, he is in a suit and white shirt. When he is at a barbecue or being casual in some other way, he is dressed more casually, appropriately to the occasion. As to looking different from the goyim, we TOOK our levush directly from them. I just saw some footage of the Jews of Poland, and the way we dress today in the Yeshivishe velt is exactly how the Eastern European non-Jews dressed. So who dressed like whom, and who looked different from whom?
