Should There be a Dress Code for Teachers

I believe there should be a dress code for teachers. If they say students shouldn't wear something they shouldn't either. Teachers need to be role models for students. They aren't very good role models when they tell a student not to wear something, but they do. They might think since they aren't students they don't have to follow the dress code, but they should. Not wearing professional clothing make them look unprofessional. Students might not respect teachers who don't look professional.
