The 'Keeping Up with the Kardashians' reality TV stars have released an additional nine pieces on Thursday (31.03.16) to their Kendall + Kylie collection as part of the #OnlyatNM programme, which is exclusive to the Neiman Marcus department stores.

The sisters, who launched a junior collection with PacSun and collaborated with high street brand Topshop to collate a Californian capsule, have now embarked on their latest range, which is inspired by the pair's favourite vintage pieces and some of their own wardrobe favourites

Speaking to WWD magazine Kendall, 20, said: "We are so excited to have our exclusive collection for #Onlyat NM. In our own way, we wanted to replicate our favourite looks and fabrications and bring them to the Neiman Marcus customer with a fresh perspective."

Kylie, 18, added: "We pushed ourselves to help curate the very best pieces to be a part of this collection. We love Neiman Marcus as a brand, so we knew we had to focus on creating timeless, chic pieces that their shopper would love."

The collection boasts a close attention to detail and includes a red cut-out dress, which costs $575, a black and white striped V-neck wrap top for $245, as well as a black silk jumpsuit as well as a pair of leather shorts, which is only available on the luxury retailer's online site.

The collection will land in all 41 stores next Thursday (07.04.16).

Meanwhile, the Jenners will celebrate the launch tonight at a private dinner at the Peninsula hotel rooftop in Beverley Hills hosted by Neiman Marcus' senior vice president and fashion director Ken Downing.
