It was after summer break, the first month in my last year of Contemporary dance BA. It was during a ballet class, the teacher asked me and a female friend to come outside for some minutes to talk. The teacher told us that she feels offended to see hairy armpits on women. We had then two options (that became an informal rule for women in the university): to have shaved armpits or to wear long sleeves in her ballet class. 
So I try to ask for gender equality to other teachers and to the director of the university. And the help was the following : "it's disgusting", no-one would like to dance with me if I have hairy armpits and that it's like this in the dance world. 
So I spent my entire last year of university having to cover my body and sweating much more than my male colleagues, who were of course allowed to present their body as they wish.
