Sisters Kylie and Kendall Jenner are already creating heat waves in the fashion industry as they model for Kardashian Khaos bikinis

They may be young but that's not stopping them. The Jenner sisters have made up their minds to start early to create a name for themselves in the fashion and modeling world. Kendall (16 years old) and Kylie (14 years old) displayed their modeling potential last week as they sported different looks from the Kardashian Khaos bikini line at The Mirage hotel in Las Vegas.

While Kendall kept things simple in a black two-piece, Kylie opted for a more eye-catching look in a black and white polka dot bikini with a hot pink trim. And as Kendall, who has more experience so far in the modeling world, tied her hair back for the shoot, Kylie left her long brunette hair loose for the photos.

Despite the fact that Kendall and Kylie are both hoping to hit the big time as models, they are also pursuing other ventures and recently announced that they are writing a book together. The girls are working with co-writer Maya Sloane on a science-fiction story 'set 200 years in the future' that they hope to release next summer.

Kylie said: "I think we will definitely get it done with how fast [the process] is going." And Kendall added to E! News: "We want to do something so different, something that we really love."
