Kendall, 17, and Kylie have also recently launched a jewellery line in the US. They are proud of their achievements, and don't like to rely on their elder half-siblings for help.
"Not much," Kendall revealed when asked how much she's learned from the Kardashians.
"I mean, with our clothing line and our jewellery line, we didn't want much input from them, just because we wanted this to be all us. We're trying to not be so involved. This isn't their clothing line. This isn't their jewellery line. It's ours. We don't want their input on it."
Kendall and Kylie regularly show off their style credentials at a whole host of events.
The pair ignore criticism from people who think they should dress more "age appropriate".
"I get a lot of 'we're trying to grow up too fast,' but the fact of the matter is we're trying to be kids as long as we can and the way I dress - I wear heels and a skirt - doesn't make me any older," Kylie said, before Kendall added: "It's jealousy mostly, too - from young girls who are our age who are saying we look too old. But I mean, I think that we understandably - in my eyes - dress a little older because of our sisters.
"We have older sisters who we've been around our entire lives. I remember being like five, six or seven years old and going into Kourtney's closet - because she has a really small foot and walking around in her heels."
