You and three friends dress up in black and spike up your hair!!!!!(hair should be black).
Have guitars and look super cool!
Thanks to Nicole for this fun idea!
For Good Charlotte you should wear a Made jacket or preferably Level27, dickies pants or Diesel, actually they just have to be black & baggy.
You need a lot of fake piercing and a Mohawk is now Gc's bois main hairstyle.
Long tall spikes would rock, wear lots of plastic black bracelets and get a guitar case! P's Converse shoes would rock for this costume!
Thanks to anonymous submitter for this addition.
