I have heard from a reliable source that it actually is a problem with the buttons because the buttons on boys and girls shirts are on the oppoaite side but GO ASK A RAV!BECAUSE I AM NOT ONE AND I DONT WANT TO BE RESPONSIBLE
are you asking for a halachic asnwer or a opinion beacuase it seems to me that most people are offering thier opinions. This is BAD if the questioner wants a halachic answer because if he/she asks and you think that you know and answer when you dont really know and they act on your answer that would be your fault! Plz plz plz do NOT ask these questions here it is not the place have you seen anyones Smicha? doyou know if they are learned? go ask a Rav your Shailos.
