Halloween Fashion Face-Off: Kim Kardashian vs. Julianne Hough

Holy sexy Halloween costumes, Batman!

This weekend, both Kim Kardashian and Julianne Hough dressed up as Caped Crusader nemesis Poison Ivy for Halloween.

On the East Coast, Kim rocked a supersexy strapless minidress covered in ivy with glittery platform pumps, a bright red wig and gold bangles when she hosted a bash at Lavo in New York City, sans hubby Kris Humphries.

Julianne had the same idea for a Halloween bash back in Hollywood. The Footloose star tweeted a photo of herself with big brother Derek Hough in an ivy-covered corset top with skintight green lamé pants, green cuffs and a brown wig.

"Halloween Costume Hint: Wearing my RED wig that I wore in Burlesque...but my character is from another movie!" she teased.

So which star had the better Batman villainess costume? And can either babe hold a candle to Uma Thurman's Poison Ivy from 1997? Check the pic below and then weigh in!
