• War Boys
To become a convincing War Boy, you're going to need to whiten up your skin with white greasepaint or chalk makeup. Darken the area around your eyes with black makeup. You can create scars on your body with special makeup that can be found at costume stores; this kind of makeup is actually quite easy to use.
As for clothing, distressed combat pants and clunky boots are a must for this costume. War Boys typically wear no shirts, but you can get creative with this costume and throw on a battered, dusty shirt or a distressed leather jacket. Accessorize with any combat or steampunk items you can find. Goggles, bandannas, belts, military or camping packs and gear; if you can attach it to your body in some way, do it. As with all of these costumes, there is no exact way to do it right. Be creative.
