The reality TV sibling have been influenced by their home state of California for their back-to-school designs for PacSun.
18-year-old model Kendall said: "Our back-to-school collection blends bohemian inspirations, and we think our fans will love it!"
Her 16-year-old sibling added: "All of the pieces are so versatile ... we're so excited to see what our fans think!"
Key pieces from the collection include a maxi-length kimono, printed romper, high-rise bell bottoms, pointelle-hooded cardigan sweater and floral-printed babydoll dress.
According to the PacSun website: "The back-to-school 'Desert Wanderlust' colour story is reminiscent of summer days setting into fall nights.
"Holding onto the last few days of summer, the collection blends the casual Cali-girl style with the wild, care-free spirit of the desert."
The teenage fashion designers will be making a number of appearances in US PacSun stores to promote their latest collection.
Earlier this month, Kendall tweeted her excitement at the new line, writing: "So excited to announce that our new Back To School Collection lands at @PacSun on Friday, July 25th!"
