Kim and Kourtney Kardashian have landed in London in their typical glamorous style as they launch their own clothing collection with high street retailer Dorothy Perkins.

Celebrating their English fashion partnership, the two famous brunettes took over Aqua club in Soho for a lavish star studded bash.

The two sisters both looked the part in their matching little black dresses from their new collection as they entered the party, which was also attended by X Factor’s Ella Henderson, Rylan Clarke and James Arthur.

Kim Kardashian decided to show off her legs in a sequin little number, leaving her long brown locks down and sporting a surprisingly more natural make-up look.

Meanwhile Kourtney Kardashian followed the British ladies’ love for tights as she covered up her legs in a pair with black dots, which matched her high-neck chiffon dress.

The oldest Kardashian sister kept her look stylish as she teamed up the dress with a fashionable high bun hairstyle.

Of course, the whole event was intended to showcase their new fashion venture, called the Kardashian Kollection, which features over a hundred pieces of clothing and accessories.

Therefore, a range of models sporting the traditional Kardashian look of long brown locks and fierce smoky eye-make-up paraded around in the clothes designed by the reality stars.

And the two sisters made sure to spend some time with their devoted fans, with both of them defying the British cold to hang out outside the venue, signing autographs and taking pictures.

Noticeably missing at the party was third sister Khloe, who also lend a hand with designing the range.

Khloe Kardashian is set to join her sisters in London tomorrow, after first completing a hosting gig on the US version of X Factor.
