It's Kim Kardashian - but not as we know her. We've all become accustomed to the socialite's flowing dark brown locks, but she gave us something all the more brighter at a Halloween bash over the weekend, sporting blonde hair to go with a figure hugging mermaid's outfit.

Kardashian was out at the Midori Green Halloween Party last night (October 28, 2012) and, though her hair was in fact a wig, it added to a striking outfit which also saw the star wearing a plunging shell bra and emerald mermaid skirt.

As you can see from the pictures, Kardashian looks pretty darn pleased with her outfit, as well she might. Her pal La La Anthony was also in attendance and it's pretty obvious that she was lagging quite far behind in the best costume stakes, her attempt at a wolf nowhere near as impressive as the 32 year-old's outfit. Before the event Kardashian had Tweeted a picture of herself in the outfit with the caption "Splash", in reference to the Darryl Hannah-starring film of the same name. There was also a snap of her with other half Kanye West, the rapper looking dapper in nautical costume.
