I haven't been to a Nevershoutnever cocert but I did go the a Nick Jonas and the Administration concert ( I know not a good compairson but w/e) and I had on a hat that not a single other person had on and Nick looked right at me and smilied (EEEKKK!!!)....so if you want to get noticed by one of the band members just look origional. If not the basic concert shirts are always good. I would vote for curly hair...just because strait hair is kind of in right now so you might stand out.
