Kourtney Kardashian - Kardashian Sisters Strip For Dash

Khloe and Kourtney Kardashian have posed naked for a D-A-S-H advert.

The reality TV stars stripped off for a new advertising campaign for the boutique chain - which they own with their sister Kim Kardashian - and have been pictured nude alongside two store workers with black dresses airbrushed onto their bare skin.

Khloe wrote on her official website: "Kourt and I came to Miami to revamp Dash, and that's exactly what we did! We worked our little tushies off and were so excited about the store's fab new makeover that we thought what better way to celebrate than by getting one of our own. Dash has never looked so good! LOL.

"It literally took ALL day to get airbrushed but it was so worth it.(sic)"

The sisters posed in front of photographer Nick Saglimbeni - who Khloe has praised for the "beautiful" final image.

She wrote: "Nick Saglimbeni was the photographer and I think he did an incredible job. He actually helped come up with the concept for the shoot and everything just turned out beautifully."

The girls' antics were also filmed by a camera crew for an upcoming episode of their reality TV show 'Kourtney and Khloe Take Miami'.
