She is on the road to becoming a very successful model.

And in between her official shoots and projects, Kendall Jenner never ceases to stop working for the camera.

The Keeping Up With The Kardashians teen posted a picture of herself modelling one of her very own designs from her and her sister Kylie's clothing line in collaboration with PacSun.

Displaying her tiny waist in the black cropped top, she Tweeted: 'On my way to a PacSun meeting wearing one of my fav tops from our new collection hitting @PacSun'.

The 17-year-old paired the item with black and white striped trousers and a matching red and white striped patent shoulder bag.

Kendall and Kylie Jenner have taken a cue from big sisters Kourtney, Kim and Khloe Kardashian by launching their own clothing line.

Kendall and Kylie, 15, teamed up with PacSun to release a clothing range aimed at teen girls.

'We watched our sisters do their clothing line (Kardashian Kollection for Sears) - when the opportunity came to us, we jumped on it. We've always been interested in fashion and all that so it was great and worked out perfectly,' Kylie said in a recent interview.

The line has a California feel, with the girls hailing from the Golden state.

Kylie and Kendall recently insisted that they're not competitive with one another.

'No, not at all. I think we're both in two kind of separate areas,' said Kendall, who is more serious about a modeling career.

Kylie, on the other hand, would like to put out her own line one day and would like to try her hand at  acting.

The teens are also taking a page from their older sisters by entering the publishing world. 

The Kardashian sisters have already released two books, a memoir and a novel. The Jenner sisters are writing a sci-fi, young adult book that's due out later this year.

One way they're not in a rush to emulate their sisters, though, is by starring in their own spin-off show.

'We're so young. I want to keep some part of my childhood private. I've been doing this since I was 9 years old,' said Kylie.
