The issue is with women looking at men, not women looking at women.
Check that with Sparkly and LuL, both of them who were discussing women not dressing Tznius.
I’m not getting why a ???? ????? would be underwhelming to you, when it’s quited by rishonim.
It isn’t a Halacha Sefer. Besides, it would not be a Chiddush that there is an Issur of Histaklus for women with the specific intent of causing Hirhurim. Even without the obvious male-oriented issur, there could still be the Lav of “Lo Sasuru”.
Just because one way in which the ???? ????? applies it doesn’t seem to be accepted (I agree), doesn’t take away from my point that it is accepted as a halachic source.
By whom? You could also be quoting me Satmar on mandated Denier of stockings.
Obviously in this instance he is not accepted by anyone in Klal Yisroel. That, and the fact that it seems to be unsourced, makes it “underwhelming”.
