Kylie and Kendall Jenner sizzle as they model their new PacSun line

They hail from the first family of reality TV.

And in a smoldering new photo-shoot for their line with PacSun, Kylie and Kendall Jenner were a glamorous sister act.

Kylie, 21, showed off her legs in a checked black and brown miniskirt and slipped into a varsity-striped white, orange and black sweater.

Accentuating her features with makeup, the lip kit icon and mother-of-one let her luscious locks cascade over her shoulders.

She and Kendall posed on stools as they leaned against a mirrored bar, shooting their best supermodel glares at the camera.

Kendall flashed her enviably taut midriff beneath a striped black and salmon tube top, slinging a black bag cross-body from her right shoulder.

The 22-year-old, who is now the only one of Kris Jenner’s children not to be a parent herself, played up her svelte legs in skintight jeans.

Her high-waisted pans were artfully torn up, and she rounded off the stylish ensemble with a pair of grey-accented white sneakers.

She was wearing a similar pair of jeans when she flaunted her figure in yet another crop top, this one plain white.

Over that top, Kendall threw on a canary yellow anorak hoodie, posing with her hands in her pockets in front of a leafy background.

Kendall also slipped into a half-turtlenecked olive green sweater, contrasting it elegantly against a grey checked button-up minskirt. 

Kylie also got an outfit-change for her PacSun photo-shoot, showing her wildness of spirit in a figure-hugging leopard print cocktail dress.

She threw on a thin charcoal jacket and let it slide beguilingly off her left shoulder, adding a touch of glitz with gleaming hoop earrings.

The two sisters began their PacSun line in 2013, and two years later gave an interview to Glamour magazine about their work for the brand. 

‘Kendall and I do just about everything with each other, but as we’ve grown up, our interests are changing,’ said Kylie, who was only 17 at the time.

‘It’s really nice to be able to spend time on something we love and work together so closely on this since we can’t always be together,’ the younger sister went on.

Kendall concurred, saying: ‘We’re sisters, so we’re always going to butt heads a bit, but at the end of the day, we respect each other’s opinions.’

She shared that ‘We’ve worked together on the collection from start to finish, so there’s a little of Kylie and a little of me in every piece.’
