Halloween [1] is, hands down, the biggest holiday for beauty-lovers (don't fight us on this one). Why? Because makeup has the power to totally transform you into whomever you want. You can turn your less-than-exciting costume into full-on fright mode with a little strategically placed black eye shadow, or bring your unicorn look to life with a few flicks of glitter. Some of the year's coolest costumes just wouldn't be complete without a face full of paint. If you're already planning out the details of our Halloween look, the YouTube tutorials ahead can help you get it right. Get your brushes out and watch along.
