M.A.C. Cosmetics is known for their glamorous makeup: available in a bewildering array of shades and renowned for quality, many items in the line don't cost much more than their higher-end drug-store counterparts. The line was created for film and photo studio use, but is quite popular with beauty devotees as well.
Now M.A.C. has created a group of Halloween costume makeup ideas, and put it on their site. There's a series of categories: Dark Side has spooky-glam monster makeup, the looks under Graphically are all patterns, the Optical Illusion category is self-explanatory (and would take a lot of skill to replicate), Pretty Things is full of more illusion makeup (feminine "masks" and animals), and Robotniks is all about our shiny metal friends.
The person who suggested this post to CRAFT said that they believed the looks could be replicated with any Halloween makeup. I think that depends on the skill of the artist. You're definitely going to have an easier time getting good results with higher-end products than you will with a $4 greasepaint palette, but these ideas are a good starting point.
However, you might not find it worthwhile to buy all the suggested shades if you only want them for one night; some of these looks require ten different products. Keep in mind that M.A.C. cosmetics have fine textures and are highly pigmented, if you're trying to find substitutes. (L'Oreal's H.I.P. line would probably be a good starting point, along with some theatrical products from Ben Nye that are available at many costume and theatrical supply shops.) Though it's not DIY, you could also always contact your local M.A.C. counter about having one of their artists try to replicate the look you like.
