Not anywhere close to an expert on this topic, but if I were in your situation, I would basically assume that you should be wearing something that you can wear a white coat over (minus the tie of course). So a button down shirt that's tucked in and slacks or dress pants with professional looking shoes. I think a short sleeve button down is probably acceptable but a polo probably isn't. You should be able to wear a tie with the shirt that you will be wearing.
Are people allowed to wear scrubs to lecture? I imagine that would be much more comfortable and easier than slacks and dress shirts everyday... not to mention the time and money saved for dry-cleaning vs. laundering those shirts at home...
