No experience with your issue, but I do have some speaking to Rabbis and Rebbetzins. You’ll probably realize this yourself eventually: they don’t always tell you what you were sure they’d say! Sometimes they say something entirely different. So maybe have that conversation with the rebbetzin after all.
If you’re a little uncomfortable talking to her, is there maybe a different Rebbetzin (or Rabbi) you’re close with that you can ask?
Because I agree like others mentioned, that the CR isn’t the best place for this.
You’ll find lots of threads here about tznius but when it comes down to deciding what to do IRL, you want expert advice and a personal consultation. Or at least that’s what I’d want…
