We can either spend a lot of time trying to figure out how the marketing machinations worked in getting Heidi Klum to play dress-up in a 3,500-square-foot Soho penthouse before her big Halloween party at Vandal New York. Or we can just revel for a moment in an Instagram pix that the “Project Runway” host and supermodel posted after the big party night.

Indeed, some fancy footwork must have been needed for Booking.com, Douglas Elliman and Klum’s handlers to make it all happen, but it did. Klum and her pals were able to use the penthouse at 94 Thompson Street for a pre-party dress-up shindig on Oct. 31 before heading to her 17th annual Halloween party in NYC. Below is an Instagram photo of Klum and friends posing in front of the penthouse’s fireplace.

According to Douglas Elliman, whose agents Tom Postilio and Mickey Conlon hold the listing for the $15.95 million co-op, Klum and her gal pals were given the use of 94 Thompson in exchange for some added-value publicity for the penthouse in the Soho Gallery Building between Spring and Prince streets. In addition to the modern splendor of the interior space, the penthouse also boasts 2,200 square feet in terraces over two levels.

“With all eyes on the celeb-sensation’s famous annual party, Heidi has been forced to step up her game each time, and she wasn’t afraid to go the extra mile for her celebrity-adorned bash this year. Seeking the perfect place to get ready for her big event, Booking.com and Douglas Elliman’s Tom Postilio and Mickey Conlon had everything the reigning ‘Queen of Halloween’ required as she prepped for her much anticipated costume reveal – a contemporary, 3-bedroom penthouse in a Soho Gallery Building with panoramic views of the Manhattan skyline,” we’re told.

While the rest of us schlubs were consigned to poorly lit mirrors in our small bathrooms to apply Halloween makeup or elbowing our way to get a peek of the outrageous and clever in last night’s parade, it’s good to know Klum and her cohorts were living it up in a free luxury digs in exchange for a little Instagram post.

As for 94 Thompson Street: Klum is gone, but the listing remains. The building was converted into a “boutique” co-op in 2000. The building has entrances on Thompson and West Broadway. There’s a full-time superintendent, a keyed elevator, video intercom, and private storage, as well as flexible policies on pets and pieds-a-terre.
