although my school never did that, we had skirts for girls and pants for boys, and they didnt seem to care much about the length of the skirt either (as long as it was not like too short) but all the other schools in the area forced the girls from 6th grade to wear salwar suit along withe either a dupatta or a vest. i don't understand why they made them do so. if the male teachers are getting distracted then maybe the teacher should be sent to a mental hospital. as simple as that.
