DGT3, In my last job I visited literally hundreds of colleges and universities over the years (including some down your way) and the majority of academic staff were smart casual, the admin staff ranged from full makeup, shoulderpads to kill with on reception to jeans and t-shirts in IT (senior staff tended to be smarter than most). I think you've got it right and would suggest possibly dressing to the workplace your students are going to end up in (schools these days seem to be smart casual, even some public schools!).
