Kylie and Kendall Jenner are ''honoured'' to have teamed up with Topshop.

The reality TV stars unveiled the campaign for their first collection for the high street retailer today (01.06.15) and confessed they were over the moon to have been asked to collaborate with the company after the opening of its first store in Los Angeles caused a ''fashion frenzy''.

Kendall said: ''I just love Topshop. When Topshop opened in our local shopping centre, The Grove, it was total madness. Everyone was dying to go to Topshop and you'd ask anyone wearing anything cool, 'Where did you get that?!' And it was always 'Topshop!' It was a total fashion frenzy. So to be involved with the brand is an absolute honour. It's very cool.''

Kendall, 19, and Kylie, 17, look stunning in the ads for the range, entitled Kendall + Kylie, which retails from £28-£80 and includes pretty summer blouses, distressed denim shorts, maxi dressses, floral playsuits and wide leg trousers.

The 'Keeping Up With The Kardashians' stars added they are hoping to see their sisters Kourtney, 36, Kim, 34 and Khloe, 30, sporting the collection.

Kylie said: ''Our family love supporting us and wearing all our stuff. Khloe would love the jean shorts.

''Kim is simple.''

Kendall agreed: ''Yeah, she would keep it pared back with our wide black pants.

''Kourtney would definitely wear our short little black romper.''

Although the brunette beauties believe they have very different personal styles they found working together on the design process remarkably easy.

Kylie explained: ''Kendall has more of that off-duty model style. She's simple and casual. I'm more of the type that would wear a dress and heels to breakfast. I'm a bit edgier and like darker colours. Generally though, we like a lot of the same things.''

The girls were also happy to share their favourite pieces from their new line which will go on sale at Topshop stores worldwide, online and in some Nordstrom stores from June 3.

Kylie told Vogue Australia: ''My favourite piece is the grey crew neck sweater that says 'When in Doubt, Vacation'. That's our motto!''

Kendall added: ''I really like the wide-legged black pants that are see-through. I'd probably wear them with a knotted up T-shirt and some strappy heels.''
