Sure you should go, but that is ages from now. You should have other options and venues in the meantime. Practice dressing up and go out 2-3 times per week until then. Learn how to wear a sport coat, tie, bow tie, braces (suspenders that button in, in lieu of a belt), a vest and a suit. Not all at once. There is a fine line between dressing sharply and trying too hard. In general, only have one unusual item at a time, and downplay the others if necessary. Remember to match the leather of your watch band, shoes and belt, and the metal color (silver or gold) of the belt buckle, watch, cuff links, tie bar, or suspender clasps.
