wellinformed : even haman knew that lehios kol ish sorer bibaiso
the man is the gavra and can have a very powerful impact on what his wife and daughters wear. on the other hand if someone trusted his wife enough to marry her he should trust her judgement on how she allows her children to dress. many teens want to test the waters and if its within the guidelines of halacha it would be wise for the parents to allow it. if my girls want to wear a longer skirt with short socks that cover the ankle in the summer and most other girls are doing that also, it would be foolish to disallow it and be makpid.
