Kim, 33, donned a Ralph & Russo Couture silver and black gown, which featured a latex body suit and a chainmail style maxi skirt with a large slit down the front, exposing Kim's legs, reported the Daily Mirror.
The actress said the original dress was much less revealing.
"I was wearing this stunning dress, but they chopped off my sleeves and wanted to show more. I'm just going with it," she said before the event.
