I’ve finally chosen my Halloween costume

I’ve decided to go as Anonymous.

I bought a Guy Fawkes mask, so now all I need are the clothing. I am thinking a black sweatshirt and black pants, no labels in sight. The problem is going to be finding these things. I am going to try the thrift stores and the army surplus store. I hope they are there because the only other place I can think of to get label free black clothing would be Wal-Mart, and something tells me that’d defeat the purpose.

I am thinking of wearing a black backpack, too. I am not sure.

Ideas?
