I never understood how telling someone to dress professionally for a professional environment is "sexist" especially when the rule applies to both genders. Girls who call it unfair or sexist ask yourself how many guys do you see walking around in tank tops (outside of gym) and in shorts above thighs? The ratio of guys who dress in such a revealing manner vs girls would be about 1:10 and this is obvious to anyone who has been in public. I find it funny that guys are usually better at following dress codes and most of the time wear tshirts or shorts that arent above knees even in hottest weather despite men having more body hair than women which would make them hear uo more but girls find a way to complain about this and demand special rights to basically go half naked in a professional environment. Girls who call dress codes "sexist" should reverse their role and ask themself would it be inappropriate if they wore crops, loose tank tops or booty shorts if they were a guy? And if answer is yes then it's not sexist you're just whining about special privilages because you don't like adult authority telling you to do the right thing.
