Halloween Costumes 2011: Kim Kardashian Dons 'Poison Ivy' Costume [PHOTOS]

Beware of Keeping Up With the Kardashians star Kim Kardashian this Halloween weekend.

Kardashian posted her new poisonous ivy look on Twitter Saturday for her followers and credited Hollywood makeup artists and stylists Monica Rose, Joyce Bonelli, and Rob Scheppy for the Halloween look.

The reality-television icon is hardly identifiable in her Halloween costume, which she will wear to a Midori-sponsored party in Las Vegas.

Glamming up for my Midori Halloween party at Lavo tonight! I have bright red hair! OMG this is kray! she tweeted.

The Halloween get-up features a red wig with a dress made of glossy green leaves.

Seriously @MonicaRoseStyle @jOYCEBONELLi & @robscheppy worked their magic on my Halloween costume this year. They did their THANG!!! she wrote.

Rose, Bonelli, and Scheppy are makeup artists and hairstylist who are mostly recognized for working with the Kardashians.
