So there s the Kardashian trio (and their overbearing fame-hungry mother), and then there s their half-sisters Kendall and Kylie Jenner, ages 15 and 17.

Currently, these two girls act as fashion contributors for Seventeen Magazine and are constantly doing runway and modeling gigs from L.A. to the Big Apple.

In the family s reality show, Keeping up with the Kardashian s, we saw both girls struggle to keep their grades up in school. After much begging and pleading, mom manager Kris Jenner and former-Olympian father, Bruce Jenner, enrolled the girls in a home school tutoring program.

Given that the sisters are known for their trendy fashion, the young teen duo definitely has a head start when it comes to fashion and brand building Kendall and Kylie will be rolling out their very own clothing line this coming February 2013, exclusively in PacSun stores.

While the details aren t all that public yet, some of their campaign shots have leaked. We can expect the clothing line to give off a sunny, chic California vibe with flirty bohemian flair.
