Who Is Poison Ivy?

I'm going to show you how to make your own Poison Ivy costume for Halloween, but first I'd like to introduce you to the greenest Halloween costume around.

Poison Ivy is sexy and diabolical. This seductress was once Dr. Pamela Isley, a botanist with a background in toxicology.

She was once human but now she is half-woman, half-plant, and 100 percent lethal. Ever heard of the kiss of death? She has it. Stay away from this redhead because her first kiss is deadly. Her second kiss can save you—but chances are you won't get that far. Her touch is also deadly, so if you see her coming, you'd be smart to make yourself scarce.

Poison Ivy loves plants, and she believes they have the right to live without being harmed. She can communicate with plants; she can intuit what they feel and they will help her whenever they can. She takes her convictions to a new level with her powerful touch or kiss that will kill you. She thinks men are the weeds in her Earthly garden, and she will do whatever it takes to protect her "children," which she considers the plants to be.

"It's not nice to fool with Mother Nature."

— Poison Ivy

What Is Poison Ivy's Story?

Funded by Wayne Enterprises, Dr. Pamela Isley was a botanist who loved plants and was researching ways to protect them. Working alongside her boss, Dr. Jason Woodrue, she was experimenting with poisonous venoms and fluids, but her experiments were failing.

Dr. Woodhue, it turned out, had his own agenda. As Dr. Isley formulated different poisons he would take samples of each one. Dr. Woodhue found Dr. Isley spying on him one day, causing him to attack her. He knocked her out and left her lying in the poisons and venoms that she had been experimenting with. It didn't kill her—but it did make her crazy. (You've heard the old saying, "what doesn't kill you makes you stronger?") But more importantly, it transformed her into the villainess we all recognize today as Poison Ivy.

"So many people to kill . . . so little time."

Choose Your Poison (Ivy Costume, That Is)

Take a good look at all the costume pictures on this page and then read over all of my tips for how to assemble different variations of this costume. You can choose a costume exactly as it is shown in one of the photos, or you can take pieces from each costume and combine them to make your own unique look for our villainess.

It will be challenging and rewarding to put together your own costume look this year. I love the cape, so I would include that in my costume. There are so many great ideas to pick from. Pants, skirt, or dress? Leotard base? How about that cape? Will you choose clothing in the same green color or go for different shades of green? You've got a lot of decisions to make!

You can find ivy wraps that wrap around your thighs, stockings with an ivy pattern right on them, and lots of other great ideas. Be sure to look at all the pictures when you are planning which outfit to make.

DIY Poison Ivy Costume #1

You can see from the pictures on this page that Poison Ivy is dressed all in green and everything has ivy leaves on it. Her hair is a lovely shade of red—and yes, I'm biased since I too am a redhead.

Here's what you will need to make this easy costume at home:

Read More From Holidappy

  • Green leotard or spandex jumpsuit or dress
  • Green tights (they can be fishnets if you can find them)
  • Green silk leaves that look like ivy (to attach to the outfit)
  • Needle and thread or hot glue gun and glue sticks
  • Green headband (optional)
  • Green gloves (optional)
  • Green cape (optional)
  • Green or black shoes or boots

You can decide if you want to wear a top and pants, a dress, a leotard, or a jumpsuit-style costume. Take ivy leaves and glue or sew them onto your top, your pants, and leave some for your hair, too. The cape and hairband are optional. Sometimes Poison wears long green gloves—personally, I like that look, but since it's your costume I leave that decision up to you.

Poison Ivy and Harley Quinn are bad BFFs

Poison Ivy and Harley Quinn

Poison Ivy's only human friend is Harley Quinn. These two are both doctors—and villainesses. Each has their own axe to grind with Batman, so he is a common enemy for them. They like to hang out together and they also enjoy going on crime sprees around Gotham.

Some newpapers call them “The New Queens of Crime." Harley simply calls Poison Ivy "Red."

Harley, Poison, and Catwoman are sometimes called "The Gotham City Sirens." These sultry, sexy ladies would make a great group Halloween costume idea.

Poison Ivy: "Crazy...!"

The Joker: "I know you are, but what am I?"

Poison Ivy: "You will just *have* to find out!"

Poison Ivy Makeup Ideas

Poison Ivy's makeup, like her costume, is green, and ivy leaves are a must-have. You can create some really interesting looks when you dress up as this gorgeous villainess.

  • Hair: Her hair is thick, long, and red as can be.
  • Skin: Her skin is green and has leaves growing out of it.
  • Colors: Lots of shades of green. Some for your face, neck, and shoulders. Some for your eyes.
  • Eyes: Get a green eyeshadow set so you have different colors to experiment and shade with. Take a look at one or both of the makeup tutorials I have posted below.

Many of the pictures on this page are of Uma Thurman, who played Poison Ivy in the movie Batman & Robin, released in 1997. Poison and Mr. Freeze were the villains in this film and the usual bad guys and gals, Joker, Penguin, Catwoman, and Riddler, did not appear in this one.
