go with the gorilla suit
My fav costumes ever
1) Party boy with throw-away pants and bowtie
2) With a bunch of friends all come dressed up as english gentlemen with brown jackets, monocle, pipe, stache, flask, etc
3) Rapist, in one of those long grey trenchcoats with a hat and dark shades
these costumes are also fun to wear all night, whilst compared to animal costumes, they can become very obnoxious and hot...
