A few miles northeast of Manhattan’s Meatpacking District, a drone circled the abandoned Roosevelt Island building that once housed a smallpox hospital, capturing the scenery below. It was there that Kanye West staged his Yeezy Season 4 show on Wednesday afternoon, and the Kardashian clan — Kim, Kylie, Kendall — was in attendance.

But Yeezy was running more than an hour and a half behind, and back downtown, a few (hundred) of Kendall and Kylie’s biggest fans had started to queue up outside the Samsung 837 flagship on the west side of Manhattan. While the sisters waited for the Yeezy festivities to begin, the crowd grew, hoping to catch a glimpse of the duo at the launch of their newest collection for their Kendall + Kylie line.

Inside the quasi-futuristic space, slow-motion scenes from the Kendall + Kylie Fall 2016 promotion video were projected from a three-story screen; on the bottom floor, a DJ spun an array of hip-hop throwbacks while upstairs, guests sipped cocktails and perused the new collection, gathering around several artists who had been recruited to embellish, personalize and airbrush the clothes.

“We always learn something from Kanye,” Kendall said when they finally arrived — tardiness apparently being one such thing the budding young designers seem to have learned from West. “It’s just awesome to see his creative mind just burst into clothes.”

They had changed out of the neutral uniforms they had donned for Yeezy in exchange for pieces from their own line: Kylie in an ivory crop top with a blue-and-white striped pajama set and Kendall in a black silk track suit. Yet when asked her thoughts on athleisure more broadly, she paused.

“What does that mean, exactly, again?” she asked. When I offered a definition, she jumped in again — “That’s me,” she said. Kylie echoed her: “I think that’s me, too.”

The event was live-streamed and the Fall 2016 collection was immediately available, embracing the see-now, buy-now model that has also become the modus operandi of Tom Ford and Christopher Bailey at Burberry. The sisters’ upcoming Spring 2017 look book was shot at a historic Beverly Hills estate called the Greystone Mansion, rumored to be haunted. One might also venture that the smallpox hospital on Roosevelt Island where West staged Yeezy Season 4 might also hold its share of ghosts.

“I think I believe in ghosts,” Kendall said. “I feel like I’ve had little encounters.” Kylie’s shower occasionally turn on in the middle of the night; doors close without warning, with no one around — “Just weird stuff,” Kylie said.

At exactly 7:30 p.m., the girls were still submitting to interviews and the DJ began to spin Kanye West’s “Fade.” (Teyana Taylor, the star of the video, walked the Yeezy show earlier in the day.) Models, like Doutzen Kroes and Joan Smalls, and Kim Kardashian stopped by to congratulate the sisters — and maybe, even, to get first dibs on Kendall + Kylie Fall 2016.
