Here's my interpretation of a Harley Quinn look for Halloween. This is based off a design I saw on Tumblr, the original artist is named Luciferismydad. It's a more artistic version than the plain ol' black mask, which is kind of boring, in my opinion. See my tutorial how I pulled this off, or watch it directly on Youtube.
Here's all the products I used:
MAC Airbrush foundation in White, L'Oreal Magic Lumi foundation, L'Oreal Infallible Super Slim eyeliner in black, Maybelline Color Tattoos in Timeless Black and Pomegranate Punk, Ben Nye Cherry Red e/s, Illamasqua Obsidian e/s, Kryolan e/s in burgundy color, Ben Nye Toast e/s, Sleek MakeUp Russian Blue eyelashes #233, Manhattan Xtreme Last Lipliner 44N, Illamasque Pure Pigment in Berber, L'Oreal Infallible gel eyeliner
I hope you try out this look and let me know how you like it!
