Kim Kardashian donned a glittering tail, seashell bodice, and a blond wig as she dressed up as a mermaid — more like the "Splash" mermaid Madison, not "The Little Mermaid's" Ariel, as she specified on her blog — when she hosted the 2nd Annual Midori Green Halloween at NYC club Avenue on Saturday. Kardashian's date, beau Kanye West, who often coordinates his look with his lady's, sported a nautical-themed ensemble.
