the tznius is horrible in the frum world the truth is we should just look down on the street and not complain becausee are not changing the world.
but why do ladies dress like this they think tznius is just covering the parts where you have to. the truth is making one to try look at you and get their attention is also a problem with tznius. in halacha it says not to dress in red because that attracts the eye.
Husbands and fathers have to convince who they can to try to dress properly as this story with Rav Schach zt”l shows a man once complained to Rav Schach that his wife is not dressing properly. Rav Schach said to call in his wife. When the qwife came in Rav Schach said her husband complaint she replied that the only time my husband complements me on how i dress is when i dress not properly.
About a year ago there was a roumor about moshiach coming ( with Rav Eliyashiv shlit”a) a lady called a Rov and said she does not want moshiach to come yet because she has nothing tznius to wear. Its a true story. I hope when mashiach comes, we will have some thing tznius to wear to gret him and when we do he wont push away ladies (AND MEN WHO ALSO DRESS TO SHOW AND TO ATTRACT ATTENTION) because they are not dressed properly. may we be zoche to mashiach very soon
