Interview vs. Open House Attire

[futureslp112]

I attended a few interviews in the past couple of weeks and dressed business casual.  Now I've been invited to a couple of accepted student open houses.  How should we dress for these open houses? At first I figured I would dress similar to how I did for my interviews, but one of the schools said they are having a pizza party, so I'm assuming that means more casual clothing.

I am going to do casual because I don't see open house as very formal events. It's just to get us to know the schools better, and I know that students dress pretty casually when they go to class (not clinic) so I don't think it would be a problem.
