Wolf-i agree with you a thousand %. i don’t think takanos on stores will help. Everyone has to be honest with themselves and determine whther they are tzniyus or not; and unfortunately that is the minority.
Another thing that bothers me is some HUSBANDS allow their wives to dress innappropriate. Someone just told me that she went to buy a dress and she knew it was too short but her husband told her “it looks great on you, nu so don’t sit with it!” and she bought it! true she knew it was short but her husband allowed it! i am a little shocked, because i know her and she is frum. Anyway she told me that her teenaged daughter told her respectfuly that its too short so she said its good chinuch for her daughter so she will lenghten the skirt! i wanted to tell her shes a little mixed up – lengthen it for yourself, so YOU can dress tzniyus!
