The reality TV star explained the new Kollection is meant to fill a void she and her sisters noticed in the UK fashion market.
"We wanted to offer something different to what currently exists on the British high street," she said. "We spent a lot of time trend forecasting and collaborating on ways to design a fresh line of fashion-forward, affordable luxury. Kardashian Kollection for Lipsy will have some amazing standout pieces like a full lace jumper and metallic sequin jackets."
Kardashian added that her favorite outfit in the collection was a lace monochrome dress that has scalloped edging.
"It's very feminine and will be a great style for holiday parties," she explained.
Regarding the design process, in which her sisters Kim and Khloe are also involved, Kardashian explained that three heads think better that one.
"The Kollection is a complete mix of Kim, Khloe and I. Each of our individual styles are reflected and that has been the way we have always designed."
"We are constantly emailing each other with ideas. Three minds think better than one sometimes. Working together as sisters is the most rewarding part of having a line together. There are times when we disagree, but we always respect each others opinions and ideas.
Asked if she had any fashion regrets, the mother of two said "there have been so many."
"But I don't consider them regrets," she said. "Fashion is so subjective and I think it should playful."
The Kardashians' latest Kollection is set to launch in the United Kingdom on October 24. For Kourtney Kardashian's full interview visit HelloMagazine.com.
