Went to the 2013 Zombie Crawl in Denver, this was my costume.
Some old pants and a shirt, an over shirt from Goodwill, $1 elastic bandages, flannel handkerchief made from fabric from Jo-ann Fabric.
Add a little grease, mud, oil, paint, ink, and fake blood.
Stir with a grinder till shredded, Then bake till burning with a blowtorch.
And WHALLAH! you have your very own zombie apocalypse survivor outfit!
I think it came out rather well!
