The sisters spoke with ET at the launch party for their new clothing line, Kendall + Kylie, in New York City on Monday, where they opened up about stepping into the role of fashion moguls.
"We just decided it's something we wanted to do on our own and give the fans exactly what they wanted from us," Kendall told ET's Carly Steel of their new collection, which she called "our more mature, stepping-it-up line."
While their brother-in-law, Kanye West, who showed up to offer his support, has already found success starting his own brand of high-end footwear, the girls said they didn't reach out to him for help. "He is so creative but he didn't give us any advice," Kylie shared.
"I don't think we wanted anyone else's opinion other than ours," the 18-year-old reality star
added. "We wanted it to be really organic and truly representing our styles."
That doesn't mean the girls didn't find inspiration in the style icons who have come before them. "I love ‘90s Kate Moss style and I love Miranda Kerr's style and Rosie Huntington-Whiteley," Kendall shared.
She also admitted that they were inspired by their older sisters, Kourtney, Kim and Khloe Kardashian, because they're "surrounded by [them] every day."
When asked what she’d say was her job title, Kylie didn't hesitate with her answer, "Businesswoman." But she also proudly boasted that she's like a "mini-Kris Jenner." Hear that, Kris?
