I personally knew of a very choshuv Rosh Yeshiva years ago who would stand by the Beis Medrash door before Shabbos Mincha and send any bochur not wearing a tie back to his dorm room. The “tieless look” is no more than a mishigas and laziness. It is still Shabbos at that time, no reason to dress down.
shmendrick- sorry, but your comparison of women’s jewelery being parallel to a man’s tie is a (bad) excuse and nonsense IMHO. You dress with a suit and tie from Friday night till Havdala Motzei Shabbos, period. Your first post was brilliant and you seem like a talmud chochom quoting those marei mekomos and being dan l’kaf zechus for all those who go tie-less. But I don’t buy it.
