Kendall and Kylie Jenner will debut their summer fashion collection on June 22.

The sisters posted a video revealing the new designs for their PacSun line, including crop tops, T-shirts, overalls and jumpsuits.

Kylie, 15, said in a video posted on Keek: ''We're very excited about it: Here's a little sneak peek'', before showing her fans a couple of their products.

The summer collection is the second collection the sisters have released for the west coast surf brand, after their first, released in February, was such a huge success.

Kendall and Kylie hot to fame, along with the rest of their family on reality TV show 'Keeping Up With The Kardashians' and were at one point rumoured to be starting their own spin-off show for E!, although Kendall, 17, was adamant her focus is on fashion.

She said: ''That's not happening. Modelling is my number one priority - one hundred percent.''

The duo's half sisters, Kourtney, Kim and Khloe Kardashain also have their own 'Dash' clothing stores, with branches in Miami and New York.
