Kim and Kourtney Kardashian launch Kardashian Kollection

Kim and Kourtney Kardashian launched their Kardashian Kollection with a glamorous party in London last night (08.11.12).

The stylish stars - who, along with sister Khloe, have teamed up with British high street store Dorothy Perkins for the clothing range - joined British businessman Sir Philip Green as they partied at the city's exclusive Aqua club, while wearing clothes from the range.

Before they arrived a range of Kardashian lookalike models, sporting the look of long brown locks and fierce smoky eye-make-up, paraded around in the outfits designed by the reality TV stars.

The girls say they have been very impressed with British fashion since being in the UK and can't wait to see girls wearing the Kardashian Kollection.

Kourtney said: ''It's not like matchy-matchy, everyone in the same thing, it's very different.''

Kim added: ''It's amazing. I think they have such great style, very effortless and chic, that's why we're really excited to launch here in the UK.''

'X Factor USA' co-host Khole is set to join her sisters in London today (09.11.12) ahead of the girls meeting fans as they launch the collection at Westfield shopping centre in west London tomorrow (10.11.12).
