I am teacher, that's why my main dress-code rule is "no wear black". I should observe it because I use a chalk. White chalk crumbles and rains from blackboard to my clothes. That's why I will dress out this black jacket in my classrooms and I will put it again in cold street air. Also I wear often stone-washed jeans.
