She was allegedly kicked out of her school's gym for not wearing a more conservative shirt. http://metro.co.uk/2017/04/25/this-uni-student-apparently-got-kicked-out-of-her-campus-gym-for-wearing-athleisure-6595682/
just a bunch of people wanting to police other people's personal choices. those people never die out and the best solution is to give them the finger and keep doing your thing. :)
It sounds as though there might have been a dress code against showing too much skin. There have been numerous cases in the UK about students refusing to adhere to dress codes and I suspect this may be one of them. Rules are rules.
Good for the school! Having and enforcing a dress code is just fine in my book. They should enforce every rule. The gym is a dirty, sweaty, germy place. If she wore this to class I'm wondering why professors didn't dismiss her.
