Why reinvent the wheel? This is the thread you’re looking for and I gave several suggestions on how to be marbeh tznius and taharas eynayim in klal Yisrael.
#1: MAKE THIS A PRIORITY. Don’t push it under the rug because it’s the nine days and similar excuses. Never hold up a less-than-tzniusdik woman or girl as a role model, no matter how good she’s “inside”. Tznius is an “outside” mitzva just like talis and teffilin.
#2: RAISE YOUR STANDARDS. Bare-bones yiddishkeit is not good enough. ??? ????? ????? ??. Zero tolerance for leitzonus of those who are on a higher madreiga of tznius. Praise them for it, hold them up as role models, even if you’re not up to it yet.
