The great thing about Halloween costumes is that you can put a zombie twist on any of them. For teens, a zombie prom date may be especially apropos. To find a dress or tuxedo, they should check out local thrift stores; that way, they won't mind dousing it in fake blood and dirt for special undead effect. Girls can pick up a tiara as well and go as a zombie prom queen. Makeup and hair are crucial for looking like a convincing zombie. Use dark green, yellow and brown eye shadow around the eyes and cheekbones for a ghoulish appearance. Mussed up hair is also an essential finishing touch.
