Are you on stage with the same clothes you go to lunch in? Are you the kind of guy that dresses up a little,? Or a lot? Flamboyant? Is wearing shorts on stage blasphemy, or could you care less if your chicken legs are showing? Sunglasses inside? For me: Slim Jeans (not too tight, but not baggy at all), a plain t-shirt (usually black), and my converse (black). If it's not hot out I'll wear my black leather jacket, or my denim jacket. Sometimes ill wear a button up, and boots. NEVER shorts, not even in my regular, non-gig days, even in the middle of Summer.
