“it’s not about shallowness…
it’s about the society.”
Society can be shallow. Anyone involved with shidduchim, whether for themselves, their child or as a shadchan knows this 1st hand.
I learned in yeshiva (and even bichavrusa with one) with several Rabbeim of YTY, they all wore white shirts only on shabbos and yom tov (or for occasions that called for “shabbos clothes – such as a simcha or a date). Now, they would lose their job faster than you can say “get out”, if they wore blue shirts, they wore in their 20s.
