DY, I know a number of Yeshivish people who were told by thier rabbonim that it is better not to attend a minyan w/o a black hat and daven at home, even if it means missing kaddish. This makes those of us who view a black hat as a fashion statement really scratch our head.
Anyway, I thought we were talking about the halacha of different sects, not the practices. Do you know any MO Rabbonim who allow mixed swimming for non medicinal purposes? I don’t! Unless you think Yeshivish rabbonim agree that the “hot chani” look falls within the bounds of Yeshivish halacha?
