I'm surprised no one else has done this particular costume (as of my writing this). I even had the perfect guitar controller accessory. I had a great surreal moment playing Guitar Hero dressed as my character in the game room too. I really like this costume, but I plan to find the right boots and right hair color for next time.
Pants - Jeans, cut off and resewn, added buttons and ribbon
Shirt - custom iron on based on in-game graphics
