Once again, as I’ve mentioned many times before, I’m grateful that outside of its Brooklyn branch, Yeshiva Chofetz Chaim deemphasizes white shirts. They feel it is important for a talmid to dress neatly, cleanly, conservatively, but growth comes from within, not from the shirt. And by the way, if you’re going to wear a white shirt, please make sure it’s clean! How many bochurim wear white shirts during the week that are starting to get a gray or yellowy tinge? Don’t tell me they wouldn’t look neater in a light blue!
Another peeve I have on this subject is men who wear the garb, black suit, white shirt, hat, and yet when you talk to them you realize that they’re weak on even basic halacha. But they believe they’re frum because of how they’re dressed. Isn’t that backwards?
