Every year Playboy has its famous/infamous (depending on your opinion) Halloween party where a bunch of girls dress in extra-slutty costumes and show off their goods. Curiously, rabbit costumes are disproportionately represented. The party is definitely one of – if not the – biggest of the year. They do a pretty spectacular Easter party but that one’s actually meant for kids and remarkably age appropriate.

So the part is a big deal – to the point that they actually hold a media preview the weekend before so that photographers can get lots of shots of the girls in their costumes to get more press. Hugh Hefner has had a lot of drama with his girlfriends, including being dumped by longtime lady friend Holly Madison. Holly is still on The Girls Next Door so she had to show up for the event. While Kendra and Bridget managed to dress in their Playboy appropriate best, Holly showed up wearing a tracksuit that screamed “I rolled out of bed and stumbled on over.”

Halloween is just around the corner which means it’s time for another party at the Playboy mansion that I wasn’t invited to. This has got to be my favorite of the Playboy parties because you know you’re going to see some great slutty costumes. Here are The Girls Next Door doing their best to stay in the spotlight. I guess Holly Madison’s upset about Hugh Hefner’s new twin girlfriends because she decided to dress up as a girl on her period. Worst costume ever!

I just had to quote that article because it’s pretty much the most apt description possible. Although I think in Holly’s case it’s more “girl broke up with a guy” costume. She looks fake and miserable. She’s still pretty and must have put some effort into her hair and face, but c’mon, this is Playboy. Everyone’s paying attention to what’s going on south of your neck.

Here’s Holly with Kendra and Bridget and a bunch of other bunnies at the Playboy Halloween preview event on Friday. Images thanks to WENN.
