Look all of you, it’s no secret that tznius standards went way down among the bnei Torah community, as it seems this thread is spesificaly discussing. If the way to go about enforcing standards is that rabbinic should tell women what to wear, probably not. But 2 things, 1) don’t underestimate the issue, don’t mock anyone who is interested in raising awareness in this area, 2) souls Kollels can have any standard they want. (Not that it’s mart to accept a husband based on his wife’s dress code) if its too hard to keep basic tznius, that’s a nisayon that has to be worked on, not s something to be proud of that “I can wear what I want, cuz no-one can tell me not to”.
That being said, there is a famous schmooze by Reb Volba, in which there was a big tayva (in his time) for women to wear mini skirts. He told the yeshiva guys that the reason their wives want to wear this skirts is because tau guts( the yeshiva guys) want them too, and although you don’t tell them outright, they feel what you want subconsciously, so it seems its the kollel guys and husbands that really need to be the ones to work on how they would like ther wife to dres. The wife is not to blame, a wife naturally wants to please her husband.
(Btw this is something I’mstrugling Wth myself – I’m not trying to enforce anything onto anybody, just sayin’)
