Kourtney Kardashian and her sisters, Kim and Khloe are set to launch their new Lipsy Kollection fashion line in the UK on Thursday. The rumored pregnant reality TV star and her siblings stun in the new sexy campaign.

According to UK Glamour, the Kardashians have returned to fashion in a big way with their upcoming range with the British dress label, Lipsy.

The campaign marks Kim Kardashian's first post-baby modeling shoot since having North West in June. Shot by controversial fashion photographer Terry Richardson, the sisters donned very skin-tight, beautiful frocks and clothes from their exclusive 40-piece "kollection."
