Kim Kardashian kept most of her clothes on for a party held in her honor over the weekend. The Playboy cover girl was feted in Las Vegas last night, as she played host to Playboy's Sunday After Dark shindig at the Palms.

We didn't spot fellow naked model Kyla Ebbert at the bash, but perhaps the magazine is waiting to celebrate her upcoming spread with a party all her own. Southwest Airlines attendants would be let in for free.
