I'm sure most schools have some sort of dress code policy, whether it is actually enforced or not (among staff). To be honest I never received a faculty handbook so I don't even know if there is a written policy, but for the most part people in my workplace dress professionally -- we also have casual Friday once a month which would indicate all of the other days are not supposed to be casual. Some people's wardrobes really confuse me, though. One day someone will wear a blazer suit and then that same person will wear something that I think looks totally causal and really inappropriate (really tight or cleavage, etc). I always wondered if people actually get spoken to or in trouble if they wear clothes that are too causal (I'm in a HS). How is the dress code handled in your school?
