Reply To: why does wearing a white shirt make you more frum in the yeshivish world

A white shirt is no more or less frum than any other colour. It’s a symbol of where you belong or where you want to belong.
Is a knitted kappel or a rimless one or leather etc any more or less frum than a black rimmed kappel? No. But it is a symbol of where you are in your yiddishkeit. Yerushalmim wear knitted kappels, and they are very frum.
I would say he same argument for white shirts.
