There's nothing like touting your own wares - particularly when you look amazing in them.
The best bit? You'll be able to steal Kim's style for just £40 when it hits Dorothy Perkins stores, proving you don't need to have the reality star's bulging bank balance to look like her (although the hair stylist, makeup artist, plastic surgeons, and spa treatments all help).
Kourtney also looked stylish - albeit more covered up - in a floaty white dress, a black jacket and matching statement necklace.
The girls chatted to Kate Garraway about their new Kollection, and even Duchess Kate's style.
Commenting on the fact Kate recycled the Alice Temperley dress she wore back in January to the War Horse premiere last night, Kim said: "I think Kate is very stylish and it's ridiculous to assume you would wear something once and never wear it again."
Too true, Kim.
What do you think, is this look selling the Kardashian Kollection to you?
