+1, this is a world of fedoras, spectator shoes and bow ties. In the real world people dress like the dude with the hot blonde. While this is the realm of Igents, I somehow don't think that fedoras, spectator shoes and bow ties fit into the SF groupthink. But yeah, equality or near-to is best. To be honest, unless you're a really out of place kinda guy (like conservative suits at a bbq) or real poor dresser, whether you're going to be dressing too formally or not formally enough shouldn't be hard to figure out. Just pick what you think suits the place you're going to and what you'll be doing and get to the more important things.
