Ever since word of Kendall and Kylie Jenner’s newest namesake fashion line, Kendall + Kylie, hit our inboxes in mid-January (thanks to a special Save the Date e-mail), we've been waiting with bated breath to see what the Jenner sisters had in store for us. Sure, we got a preview of the lookbook that teased out Kardashian-Jenner favorites, like body conscious dresses, robe-like trenches, and gladiator heels, but it took Kendall and Kylie themselves to do the collection justice.

"I really love this T-shirt dress," said Kendall, 20, modeling a nude ruched number with a dangerously high slit Monday night at their line's Tribeca launch party, where mom Kris Jenner and brother-in-law Kanye West (below) were on hand to celebrate. "I love all our shoes," added Kylie, 18, in a sleeveless tuxedo jumpsuit, as she pointed to Kendall's knee-high lace-up gladiator heels. "There's this tight black dress that I'm so obsessed with. It fits so amazing," she continued. "It has ties up the front."

Based on appearance alone, it might seem easy to identify which pieces Kendall designed and which Kylie designed, but Kendall explained that would be an exercise in futility as the offering was a meeting of both of their design visions: "We have the same taste, but a little bit of different styles, so working with that it's easy to mesh, it's easy to blend. Even if Kylie doesn't really love something, she kind of still likes it and vice versa."

The clothing and footwear collection, which was inspired by their travels to cities around the world, like New York, Paris, and Dubai, is meant to reflect the sisters in their entirety. "This line was mainly supposed to be about us, so I think getting advice from our sisters, getting advice from anyone else would defeat that purpose," said Kendall. "We wanted to keep it our own and make it very us by blocking out all the other advice." Still, the duo would like their labor of love to be as successful as another pair of famous sisters. "We love what Mary-Kate and Ashley [Olsen] do," concluded Kylie.
