lgbg-
I don’t know or care which “rebbetzin” you spoke to about this shaila, because it’s just that, a halachic shaila-for a ROV! She could have started as many “Tznius Awarness Programs” as she likes its not for her to pasken. I spoke to an acual rov, who told me that the coverings on arms are not allowed to be skin tight. I think everyone has to speak to their Moreh Ho’roah about the issue, not their local othordox rebbetzin.
