Kim Kardashian and her sisters took on the role of models for their new Kardashian Kollection denim line for Sears. Kim made sure to flaunt her infamous curves in a snug pair of boot-cut jeans.

In the new ad campaign for the Kardashian Kollection denim line, each of the three sisters wears a pair of jeans modeled after her individual shape, according to Us Weekly.  

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

The jeans come in different washes so you can choose the fit and wash that's perfect for you! she continued.

Nick Saglimbeni was the photographer and I love the way they turned out! Shoots with my sisters are the best!! Xo.

Kim wears The Kim jean, which is a low-cut, straight-leg style that will hug a curvier woman in all the right places. Kourtney wears The Kourtney, a low-rise, slim-cut skinny jean for petite women. And, finally, Khloe wears (you guessed it!) The Khloe, a high-rise curvy fit with a boot-cut leg for taller women.

The sisters pose together in jeans and matching white button-downs, wearing their flowing long hair a bit wavy.

All three styles are made of slightly stretchy denim. Each of the Kardashian Kollection denim styles comes in two wash-options and costs $68.  

Showing off our booties in our fabulous new Kardashian Kollection denim!! Khloe tweeted Wednesday. She included a link to her personal Web site on CeleBuzz to give fans a preview of the ad campaign.

The denim line is a new addition to the Kardashian Kollection at Sears, which currently offers womenswear, belts, handbags, intimates, jewelry, sunglasses and shoes. The line will be expanding into swimwear and home goods for the spring/summer.

We are really excited about home! Home looks incredible, Bruno Schiavi, Kardashian Kollection designer, told Celebuzz January 18. There are three designs in home, everything from bed, to cushions and pillows, to bathroom accessories and shower curtains. Home is spectacular so we can't wait for that!

On Monday, Kim Kardashian helped Kelly Ripa co-host LIVE! With Kelly. The reality star even opened up about her divorce from ex-husband Kris Humphries.

Being a hopeless romantic, I wanted to believe in something so badly. If you think I really made all that money that everyone claimed we made on the wedding and that it was for TV...I'm a smart businesswoman, I would have stayed married longer! Kardashian told Ripa during the Host Chat segment. This was a bad business decision. I really didn't think following my heart would create this much backlash.

The 31-year-old said ending the marriage was a necessity. I definitely tried everything I could [to save it], but also heard stories of people who had kids and stayed married for years and it didn't end up working out, she said. I want babies and that forever love and if I felt in my heart that this wasn't right, why wait years for the same result?

Kardashian said that she found herself relying heavily on mother Kris, who divorced Kim's father, Robert Kardashian, Sr., in 1990.

My mom and dad had four kids and they split up. I couldn't even fathom it at the time but as I got older, I began to understand her a bit more, Kardashian told Ripa. Thinking of myself in that situation, if my mom had four kids and she was able to get out of a situation that she felt like didn't fit her, I think anybody could.

But Kardashian still claims to have hope for the future. I just have to rewrite my fairytale, she said.
