I'd dress casual but definitely make it look like you care about your appearance. Fix your hair, don't make it look like you just rolled out of bed. Wear cologne, get your shoes polished/cleaned. I suggest not wearing jeans but instead maybe khakis or loose black pants and a button up shirt not tucked in and a nice belt and watch. You don't want to appear formal because people will probably feel like you're a little uptight. You want to look laid back at the same time look like you care about how you look.
