Unless you're a lady, then invest in business suits and nice blouses and [insert other classy articles of female clothing because this is all I know]. I have seen guys walking in to interview with companies wearing dress pants and button down shirts which may be fine for some companies. Too bad their interviewers were in full suits aka rocking the business professional. When you are not dressed up at the same level of the interviewer, points have just fallen off your side of the scoreboard. It's always good to at least wear a tie. Dress to impress as the interviewer's perception of you is decided in the first few seconds after they see you. From there on out, your responses and personality can either weaken or strengthen their initial decision of if you may be a good fit for their company. Don't dig a hole to climb out of before you even begin the interview which is going to be awkward enough for you. Plus, walking around campus in your finest garments will no doubt result in some wandering eyes becoming strangely attracted to your aura.
