If you really like to accent your Halloween costume with some makeup, look no further than MAC Cosmetics Halloween Looks section for some inspiration. The looks they feature range from beautiful, such as this one on the left, to scary or just plain creepy with some optical illusion special effects.
Along with the look, you will see a list of products to use that were actually used to create the Halloween look on the models. And if you don't have the products they suggest, you can look through your stash and find something similar, I am sure.
