The Kardashian sisters thought that one way to show off a good pair of jeans is by wearing nothing but only the jeans.

So they actually didn't bother to wear anything and went topless to promote their new line of denim jeans.

Excited about their new launch, Kim, Kourtney and Khloe Kardashian decided to wear nothing but their jeans in a new ad shoot.

They also posted their ad pictures on their blog.

Kim explained why the sisters opted to go topless on their blog: "Kourt, Khloe and I decided to go natural for our Kardashian Kollection denim shoot with Nick Saglimbeni and pose in only our favorite jeans!"
She wrote: "I think it’s such a beautiful shot and Khloe and Kourtney both look so stunning!"
 
In the photo, Khloe poses with her hands against an invisible wall, her long hair cascading down her bare back. She pops out her posterior in a pair of denim flairs.

Kim sits on a platform beside her, a knee propped up in a pair of boot cut jeans.

Kourtney lies on the floor, her hands crossed over her chest. She lifts one leg up, intertwining it with Kim's.

"Our Kardashian Kollection for Sears denim line is officially here!! There are three styles, each named after my sisters and me," Kim wrote on Twitter.

The Kardashian Kollection Denim is available at Sears and the line promises to "hug your curves."
