Reply To: How to enforce Tznius guidelines in a Kehillah

Have a פרומע מענטש stand outside by the door of the shul and turn away anyone who shows up not dressed tzniusly.

Shuls are made for men to daven. Women may only come if they are quiet, proper, and tznius. Otherwise, tear down the mechitzah and bring the status of the shul back to how it was originally where only men are granted permission to enter. It’s as simple as that.
