Most people don’t buy wedding dresses and then run them over with their cars, at least not before the divorce papers go through. But most people aren’t Girls Next Door alum Bridget Marquardt, and most people aren’t prepping to host a Halloween party in the middle of April.

This Saturday, Eve Nightclub at CityCenter is fast-forwarding to October for a Halfway to Halloween bash and costume contest hosted by Miss Marquardt and her boyfriend, Nicholas Carpenter. The pair will be going as a dead bride and groom, complete with wedding cake, dead bouquet toss and a blood spattered puffy white wedding dress that they picked up at a shop in Downtown LA.

When the shop offered to order Marquardt the dress in her exact size, the petite blonde declined. “I was like, ‘Oh, we’re not really getting married,’” she laughs, admitting that picking out a wedding dress — even one that she planned to destroy — next to her boyfriend was a bit “surreal.”

Going to a Halloween party in 80-degree weather, however, won’t be. Marquardt is a costume party junkie from way back who once used her father’s socks to create cleavage worthy of Marilyn Monroe. These days, she’s got her own boobs and plenty of custom-made costumes that show them off — like the sexy vampire bat number she designed for her appearance as Grand Marshall of last year’s Fantasy Fest in Key West. “I want to do my own line of Halloween costumes,” adds Marquardt.

While the Halfway to Halloween party won’t make it onto Marquardt and Carpenter’s upcoming reality show (not on E!), which begins filming in three weeks, that doesn’t mean you won’t see her undead formalwear sometime in the future. “I keep every little thing. To me it’s like scrapbooks,” says Marquardt, who compares herself to the people in the TV show Hoarders. “That’s what my wardrobe room looks like. It’s all costumes and props. It’s ridiculous.”

Of course, if we had her costumes we might keep them around, too. After all, you never know when you’re going to need a bloodstained wedding gown for a More than Halfway to Halloween party in, say, July.
