I'm going to go against conventional hacker wisdom and say that if you are comfortable in a suit, wear a suit. As long as you are also completely comfortable being the only one around in a suit - and that is an open question.
I think part of the problem with hackers wearing suits is that they tend not to be comfortable in them, and they tend not to fit well, so they don't look quite right in them.
Personally, I like to wear nice jeans with nice shoes and a nice dress shirt, all which fit me well. It's somewhere between casual and dressy that's not the standard "business casual," and it's a style of dress I am comfortable in.
