I know you loved this look! So I decided to do a tutorial for you !
This look is so unique, and original for Halloween.
Begin by applying your white chromacake over your entire face. It's good to have something protecting your hair so you don't get paint all over it.
Now take your white liquid paint, and instead of using a brush; Pore it into your hands, and spread it all over. The reasons why you're doing this is so you won't have any streaks on your face. It also gives the white paint more brightness.
After cleaning your hands. Add in your sclera contacts before moving onto the next step. So because the drops will end up being black, fill in your bottom water line with a black eyeliner. You don't want black tear drops with a white water line. If you want you can add a red liner to your top lid. Just because they had it in the picture, but I don't think its necessary. When that's done take your empty eye drop container, and open it. Add in some black liquid paint with a little bit of water. NOT TO MUCH! Then close it up, and shake it. Now you can begin applying your black tear drops.
Put on your costume, and you're done!
