See Kim, Khloé and Kourtney Kardashian's Sexy New Lingerie Ad!

Reality stars strip down for promotional shot touting their Kardashian Kollection Intimates line sold at Sears

Now this is one hot welcoming party!

Standing at the entrance of a very ornate doorway, Kim, Khloé and Kourtney Kardashian struck a scintillating pose in skimpy lingerie in this new ad for their Kardashian Kollection Intimates line.

In the ad (shot before Kourtney's second pregnancy, natch), Kim and Kourt flaunt their curves in pale pink and black lace bra-and-panty sets, while youngest sis Khloé rocks a black corset with a garter belt.

And all the ladies sport sheer thigh-high stockings.

"My sisters are I are excited to reveal our new ad for our Kardashian Kollection Intimates!" Kim wrote on her blog.

Kourt tweeted, "Getting intimate with Kardashian Kollection lingerie! Love this new shot of me and my sisters!!"

And Khloé added, "OMG how fab is this new ad for Kardashian Kollection lingerie?!? Nothing makes me feel sexier, plus it's all so comfy! Killing two birds with one stone! LOL."

This isn't the first time they've dared to bare together. The ladies also stripped down for their first sultry lingerie ad last fall.
