This is Redditor CarlyPaigeMakeup's Jack Skellington face makeup job. It took me a minute to realize what I was even looking at. Thankfully, there's a composite shot of the makeup application process so you can understand just what's happening here. Then, since you haven't come up with your own costume yet, you can try to do this yourself last minute, completely and utterly fail, and decide to stay at home tonight with the lights off. "That party was probably going to suck anyways," you'll tell yourself over a bowl of candy corn.
Keep going for the application process. "What application process?" YOU'RE HIRED.
Thanks to ChaosLex, who loves chaos so much he's Halloweening as a police siren tonight.
