Kourtney Kardashian relied on her family for advice when she designer her PrettyLittleThing range.
The 38-year-old television personality has teamed up with the online fashion house on her debut solo collection, which boasts 32 pieces, and the star has revealed she turned to her siblings Khloe Kardashian, 33, Kim Kardashian West, 37, as well as half sisters Kendall Jenner, 21, and Kylie Jenner, 20, for their "stamp of approval" when she was working on the line.
The raven-haired beauty told PEOPLE: "I see my sisters almost every single day, so while I was designing the collection, if I was going over fabric swatches and they were sitting next to me, I would ask their opinion, like confirming, 'This is really a good dress, right?' to just kind of get their stamp of approval.
"We're 1000 per cent supportive and there's no competition at all. I send inspiration to them all day. Like, if I am looking online and I see a cool '90s makeup vibe, I'll send that to Kylie.
"Khloé wrote me because she was out of town a lot when I was doing it, so I mostly showed it to Kim, but she was like, 'Oh my god, congratulations. The collection looks amazing. I am so proud of you.'"
Kourtney made her first foray into the fashion industry when she launched the Kardashian Kollection with her sisters in 2011, but the 'Keeping Up With the Kardashians' star has hinted the trio wouldn't always agree on certain styles to include in their capsule.
She explained: "With my sisters, we would always have to incorporate each other's style into the collection. A lot of times Kim and Khloé would agree and maybe I wouldn't agree, so we'd have to have a two-against-one rule."
Kourtney - who has Mason, seven, Penelope, five, and two-year-old Penelope with her former partner Scott Disick - has revealed her love of creating clothes started at a young age as she used to make her friends clothes for a night out.
The style icon said: "I used to sew my friends' clothes on the weekend if we were going out and they wanted something, just for fun. My love of clothes since I was so young - playing in my mom's closet and even my passion for interior design - has helped with this."
