The reality star, 31, donned a fire-red wig, super-high heels and an all-green, cleavage-enhancing mini-dress dripping with green flora for Saturday night's Midori Green Halloween bash at LAVO in New York City.
"The party is obviously with Midori," the liquor's spokeswoman told Us Weekly. "So I wanted to wear something green and I thought, what really is there to wear green? There's Tinkerbell or a mermaid -- and I wanted to be Poison Ivy. I like the red hair idea.
The Footloose actress, 23, also wore a red wig along with a green one-piece number with a corset-style top for a bash in Los Angeles.
