Yes, it is a big sore spot for many people, but I also feel it would promote school pride, and encourage a "dressing for education" mindset.
I am wearing my own "school uniforms" now, and other teachers are expressing interest as well. Not all, of course, and as I said before, my daughter, who is a teacher, didn't like the idea at all for herself, though her twins wear uniforms to their elementary school.
Many urban public schools do wear uniforms, but I doubt it will ever go here.
