Rockin' out has always consisted, at least in our minds, of two things — hard-ass music, and louder-the-better volume. Now we have the perfect way to show when we're in a rockin' mood with the Volume Knob Tee from Paul Frank ($28). Made from cotton and coming in vintage black, the graphic on the front shows the volume knob cranked to 11 — which is just the way we like it. Spinal Tap would be proud.
