Just as an interesting (and Nogayah) point (and to correct a misquote, as this is not my style):
The gemorah says “Barasi Yetzer Hara, Barasi Torah Tavlin” i.e., Learning Torah is the #1 method to avoid the Yetzer Hara.
The Gra points out that this does not apply to women, who do not have the same mitzva of Limud Torah (which acts in supernatural ways due to its mitzva power). He says instead that the #1 method to avoid the Yetzer Hara for women is to be Tzanua.
(My understanding): The antithesis of Tznius is to stand out (either for good or for bad). When one doesn’t feel the need to stand out, and can be in the background, it removes many of the causes of Avairos. (e.g.) Why say Lashon Hara if you don’t need (or want) anyone to pay attention to you?
The same idea applies to clothing. Don’t try to stand out and have people look at you (men or women), you will avoid Kinna (of you onto others and vice versa), Taava (of yourself onto others) and Kavvod (that you are the “best dressed”, more designer, or “most tznius”), which are all C’V “Motze Es HaAdam Min HaOlam”.
Bezras Hashem may we all (men and women) Zoche to be Tzanua, as the Pasuk says “Hatzeyna Leches Im Hashem Elokecha”.
