Halloween Costumes

I'm someone that really appreciates a good Halloween costume and sometimes the bad ones are just as entertaining. Take the slutty Gryffindor student for example. Who would have thought that someone would think to make THAT into a trashy costume? And they even managed to make a slutty schoolgirl dog costume which I think is pretty funny. Then of course you have the kid dressed as a donkey and the bear with...its legs cut off? Not sure what that's all about.
