I am curious. . to those who teach, how do you typically dress in class? Casually? Formally? I recall some teachers dressed very 'professionally' (generally in slacks and with a tie), while others were very casual and came to class in jeans and comfy shirts. What is considered the standard? What is acceptable and unacceptable (generally)? Until now I generally avoid formality wherever I can, and I'm wondering how much longer I can dodge that bullet! Thanks!
