Poison Ivy is without a doubt one of the prettiest villains in "Batman" history, despite her whole kooky eco-terrorist thing and ensaring male victims (quite literally) in her vines. Yes, the lady has ripe green skin, but she's also got some sexy curves that make men's hearts go all aflutter.
Take a look at this Halloween makeup video to learn how to create a Poison Ivy look with deep green lips and green skin.
This is really basic green makeup that you can, again, use for whatever you want! Poison Ivy, a witch, an alien, Shrek.
