Keep up with Kourtney in Asilio The Label

Where there's an awards there's an after party and despite not attending the event itself, Kourtney Kardashian was sure to head to the post-event gig in Hollywood.

She might be the slightly less famous Kardashian (despite all being very famous indeed), but Kourtney is our best dressed of the bunch. What she hasn't got in followers compared to Kim et all she has in her sense of style.

While Kim and Kylie tend to opt for the predictable figure hugging dress or body conscious skirt and crop ensemble, Kourtney always goes her own way.

As she arrived at Delilah, the star worked leather trousers paired with an Asilio The Label top and bralet set. The choker lace style finish is reminiscent of the Alexander McQueen pick that was worn by celebs the world over.

A source for Radar also revealed that Kourtney is 'ready to have a fourth child with Scott,' and has already been taking measures to prepare herself for pregnancy.
