High school girls not wearing bras?

So I saw this video on Facebook about this girl in high school who was pulled out of class four times in one year for not wearing a bra. Her male teacher said she made him uncomfortable. She felt that being taken out of class was more distracting than not wearing a bra. So her and all her friends organized a protest and didn't wear bras to school. As far as I'm aware, none of them faced any punishment from the school. What say you?
