What to wear

<p>Okay, this is probably an odd question, and I'm sure I'm posting it in the wrong forum, but here goes:
I will be heading up to Stanford and Berkeley September 15-16. I will be attending campus tours at both schools. I have also scheduled meetings with professors at the Engineering departments at both schools. They aren't interviews, just sort of meetings, and I think they will be showing me around the labs at both schools.
Which brings up the question: What should I wear?? (I'm a guy). I would assume, if I were just doing the tours, casual clothes would be fine, but I figure I will probably need to change into something more decent for these meetings. How formal do I need to be?
Thanks a ton!</p>
