I used to worry about being over dressed or underdressed for interviews or events. At some point I just decided that I'd never looked at someone else and considered them to be overdressed, so maybe there is no such thing. Dress in what makes you feel confident while also avoiding being underdressed. If you have a suit and the other person is in a t-shirt, they are more likely to think "looks sharp", or "they are taking this seriously" than anything negative (as long as you don't appear to feel uncomfortable in what you are wearing).
