Kendall Jenner Kylie Jenner PacSun clothing line

Kendall and Kylie Jenner looked super svelte and stylish on Saturday when the two model-esuqe girls went to the Glendale Galleria to promote their new clothing line at PacSun.

The winter line, dubbed PacSun's Exclusive Holiday Kendall & Kylie Collection, is the second collaboration between the girls and the Californian brand since inking their deal earlier this year.

"We're very involved -- everything down to patterns, to colours. We did everything," Kylie said about their involvement in the designing process.

They're on the right track!
