“to bathing attire, or none at all?”
I never advocated nakedness. A Religious Zionist woman in Israel with the long skirt is fully dressed as a Bas Yisroel.
3 generations ago a man wearing a hat meant that he was a solid bread earner and not a bum.

Klei Kodesh have to dress in a manner to enhance respect for their professional roles in the community.
Having every Bar Mitzvah boy dress as Klei Kodesh undermines respect for real Klei Kodesh.
If I wanted to undermine respect for the medical profession, I would dress up teenage boys as Doctors with white coats.
