While the Chasidim and Chareidim in EY have stricter tznius criteria, the Yeshivish oilem in C”L generally go with the same shittos as Rav Falk shlit”a brings in his Sefer. That’s the reason the Yeshivish girls high schools and seminaries use Rav Falk’s Sefer to teach the girls.
I don’t think so. Ask a Rov, not what Sems do.
But that was a side point. “In Town” might be more machmir due to the pull of Times Square, what do I know.
And Chassidim (I don’t know about Charaidim) are strict in some things, but less strict in others. It is (like most things) a mixed bag (and the less strict stuff will not and can not be printed in mixed company).
