A hillbilly outfit is a good last-minute choice for Halloween and costume parties. It is quick, and easy to throw together with things found in most wardrobes.
A hillbilly costume can be put together with the right clothes. Think about country wear like denim overalls, flannel shirts or even camouflage worn by hunters. If the clothing items are worn-out or torn, it only adds hillbilly flavor to the costume.
Make it look like a few teeth are missing by blackening them. A tooth-blackening wax is available for purchase. However, it is possible to get by with black licorice. Just mold the licorice around the tooth. Its gummy nature will help hold it in place. Keep a bag of licorice on hand to repair those blackened teeth as candy slowly wears away.
Hillbilly accessories are perfect for completing an outfit. A wild-looking wig, if on hand, can disguise the appearance even further. No decent hillbilly would be caught without a straw, felt or even trucker hat.
