Sometimes it seems like the entire world only cares about what girls/women wear or how they look.
for my children and in particular my girls, I would like their conversations with their teachers to be about academic subjects/intellectual interests etc. not skirt length.
I have no problem with a school enforcing a dress code that is similar to the work world - especially for senior pupils. Other than that who cares?
if I were a male teacher, I wouldn't comment on a female student's dress full stop. Too fraught with issues on both sides. If I felt a student was deliberately showing off flesh in class, I'd go to the principal as this would be a serious issue.
If I felt a student was accidentally showing off flesh in class, I'd go to the principal or nearest female teacher and ask her to deal with it. No earthly way as a man would I talk to a teenage girl about inappropriate dress or showing flesh etc. I doubt many men would do it in a work context either - they'd go to HR and ask for help.
My youngest is 13 - young for her age and not an older looking teen but she has a problem with the dress code in her school (she likes to wear shorts in the spring/summer term). Her attitude is why do my legs make a man uncomfortable? I agree. Most men wouldn't even notice and even if they do, surely they control themselves like every one else in the world should.
