Years ago went in to school to meet with one of my kids teacher, high school. This young teacher met me wearing slippers, she had an attitude to match. Found out later she was teaching in another school and was kicked out of that one and put in the school where my kids attended, for dating the football players. Does how you dress matter, yes! The problem, she was allowed to do as she pleased , and she had a history of bad behaviors. As a parent my kids would never leave the house dressed in pj or slippers for school, they had more common sense that that.
