Move to Gateshead. We really don’t have such issues here. Maybe a miniscule handful of people do – but I don’t know them. I can count on one hand the number of times I’ve seen anyone conforming to anything but the highest standards of tznius since I moved here.
Major difference, I suppose, is that in Gateshead we rarely see any non-chareidim (ie MO), since the kehilla is 100% chareidi. I think in America the chareidim are jealous of the MO who dress a lot ‘lighter’ than the chareidim, and they imitate them. In Gateshead it’s just chareidim and non-Jews, so I suppose it’s less confusing.
Having Rav Falk right around the corner might also make a difference, of course!
