It may not start off that way. But the girls in the Bais Yaakovs are usually pretty well behaved until they get out. And then of course everyone wants to look good. And then they get “into shidduchim” and everyone is dressed to impress.
I dont know how many phone calls I got about friends “Does she dress well?” No mention of “Is she tznius or not?”
I’m not solely putting the blame on the boys, clearly us girls are the ones dressing wrongly. I just dont think the boys are in the clear.
