Generally, when I'm getting ready to "shred" on Guitar Hero, I just wear something that won't get in the way of using the whammy bar (though one day, I'm going to dress up as Casey Lynch if I can amass that much leather).

Now I may have to throw on this Ryde Guitar Hero Tee ($24).

The tee, which is also available in black and white, is good for rocking inside and showing your love on the street.
