In addition to their popular reality television series, Hollywood's hottest sisters Kendall and Kylie Jenner have now created an eclectic range of clothing for PacSun's Spring 2014 collection. The beautiful sisters are chosen to be the new face for the brand as well, in order to show consumers how their designs should be worn.

The Keeping Up with the Kardashians reality stars flaunt their lean legs and flawless figures on the brand's latest ad campaign. 18-year-old Kendall, who already has experience in the fashion industry, undoubtedly seems natural at modeling, while 16-year-old Kylie gives her best try at posing for the camera.

One of the photos sees Kylie leaning against a white wall, posing beside a modern design pool. She has chosen to dress down in a very laidback, casual tomboy ensemble, wearing a pair of tiny denim shorts, matched with a black-and-white striped sweater. Kendall looks stunning in a monochrome printed playsuit with cutout details on her waist. She has completed her boho look with a black wide-rim fedora hat and a pair of oversized aviators.

Another snapshot features Kylie wearing a fringed black cardigan, while Kendall is sporting a fun Aztec print T-shirt with a pair of shorts.

Kylie took to Twitter to share her excitement about their upcoming launch. "Back at it! Can't wait for our @PacSun collection to drop on Feb. 7th" she tweeted. Kendall also added, "So excited to announce that our new @PacSun Spring collection is hitting Feb. 7th! #kandk4pacsun."

The Jenner sisters' PacSun Spring collection is set to be available exclusively at PacSun stores and PacSun.com from Feb. 7.
