Anyways – Don’t become Frey in spite of human beings. There are people who don’t know how to give Mussar -so they end up doing to you what you described. I’ve talked about how to give Mussar properly in many topics. These people should Not do what they do to you -either they should learn how to give you Mussar or ignore you totally. But sometimes you might be reading into their reactions. Sometimes people will do a double-take when they see a “Frum” woman who isn’t dressed Tzinus, but it isn’t meant as a put down.
Mussar has to uplift the person to correct their wrong doings.
All I can say to you is remember – A Bas Yisroel is a princess. If you wouldn’t walk around the King’s courtyard dressed the way you do -you shouldn’t dress like that in public. First realize how great you are and then you’ll always want to do the right thing!
