All ya need for this is a couple of shirts that say F@ck Off or die.
It's great for my old lady matching shirts n all.
Everyone will stay the hell away which is good for her since she's a beginner. Lol
A buddy of mine used to make his own shirt to wear at punk rock shows - He would get a tee and rip the sleeves off it, cut a v in the neck, and spray paint in red: GOD TOLD ME TO SKIN YOU ALIVE. You just reminded me of that. Good times!
