Popa says it is all about context.
If you are dating a guy from Lakewood, your principal question is whether you want to date a guy from lakewood- not the fact that he wears white shirts. Of course he wears white shirts, he is from lakewood.
If you are dating a guy from YU, your question is whether you want a guy from YU.
I really don’t see how the shirt color issue could ever come up. You aren’t going to find a guy in lakewood wearing colored shirts, and you shouldn’t fool yourself into thinking that a guy from YU is not YU because he wears white shirts.
