These characters are from West Virginia so think coal miner/trucker looks. Each character should bring several options and stay away from all black or all white or thin stripes (thicker stripes and plaid are good).
My oh my, what a stereotype! Adding further insult to injury was the fact that the ad wasn't even shot in West Virginia. It was made entirely in Philadelphia. So much for "grass roots."
