all thoes shirts are made BY hot topic, not the bands. So of course hot topic makes every shirt look like that becase thats what all the teenagers want.
Even if that's the case.. shouldn't a band care about what the shirts end up looking like? I mean a shirt is a walking billboard, it's one of the few "real life" ways to promote your band nowadays. Regardless of the style of music if someone said check out this band on my shirt and the shirt had vibrant colors, diamonds, dinosaurs and such plastered all over it, i wouldn't give them a chance.
