Dressing etiquette for interviews in academia Are there expected dressing norms at faculty interviews? Will a casual tee-jeans be discouraged?

In the same vein, what is expected when a student visits the campus for an interview?
While its not mandatory to wear a suit for a faculty interview, it doesn't hurt, and may actually be expected in certain disciplines. Best to ask around beforehand. I've never heard of a dress code for student visit, but something semi-formal doesn't hurt. 

As a general principle, it doesn't hurt to be more dressed up than necessary. The reverse can often be embarrassing. But as with most such thing, the departmental culture is the most important factor.
