One of the most whimsical Halloween costumes is the enchanting fairy. Searching online, you might find a lot of green makeup looks, but to get the full fairy look, you can experiment with hues of purple and pink. Find the longest lashes you can muster, some pigment, and a flower crown, and you're all set. The real key to this look is extending the shadow past your eyelids and above your brows but also bringing it underneath the eyes, similar to a painted-on mask. Expert tip: create texture on the "mask" by splattering a mix of isopropyl alcohol and pigment on the skin with a mascara wand or toothbrush — just be sure to keep your eyes closed during the process.
