It looks like Heidi Klum and Kim Kardashian called each other up so they’d be matching!

Project Runway was filming today in Battery Park with Heidi Klum and guest judge Kim Kardashian. Heidi wore a skintight black dress with leggings and Kim wore a short skintight black dress without leggings which accentuated her booty.

While Kim did everything to keep everything covered up, an elevated chair and a short dress are never a good mix. The reality star indadvertedly flashed her panties.

We can only wonder what Tim Gunn had to say about Kim’s wardrobe oops. The respected style guru made headlines when he called Kardashian “a poseur” in a TV interview, adding, “I find that when she’s static and still, she has an attractiveness. I find that when she’s moving, it all goes away from me.”

He also had harsh words for Kardashian’s family, stating, “I just think the Kardashians have an absence of taste, and I don’t think that that should be perpetuated.”
