There are lots of reasons for a dress code, some good some stupid. I think that if a person came in to see me and looked like a street person it would tell me a fair amount about that person's judgement and would raise issues about whether I could trust him with a client. It is sort of like being on time. Does five minutes matter? Not really but it speaks to a persons respect for you and willingness to do what is expected without a whole lot of explination.
While I agree that a star can get away with more than the average employee, you reach a point where it simply isn't worth it. A person that prides themselves on their propensity to show up at interviews looking "different" has, IMO, a bit of a self obcession and that is a warning sign. Similarly if a person opts, given ignorance, to dress down when the environment is more formal I would guess that the person took a guess as to what was appropriate and guessed wrong. In general, one cannot go wrong by being too formal.
Naturally if your interviewees are right out of college they may not own a suit. No harm, no foul. Personally, I would far prefer to see a person neatly dressed casually than in a crappy, ill fitting, off the rack piece of crap suit. But that's me.
