What’s the point of debuting a bunch of Capezio-inspired leotards at New York Fashion Week if your mother-in-law isn’t going to show up?

Kanye West made every big name in fashion leave Manhattan (on a chartered bus) on September 7th to attend his Yeezy Season 4 show on nearby Roosevelt Island.

It was a far cry from February’s spectacle, held at Madison Square Garden and attended by every member of the Kardashian family.

This time, Kris Jenner and Kourtney Kardashian decided to take a vacation in Italy, and Khloe was photographed on September 5th in Mexico with Cleveland Cavaliers forward Tristan Thompson, 25.

Even though Kendall and Kylie Jenner attended the show (they are promoting their own brands at Fashion Week), it would have been nice if the whole crew showed up.

“It was a big disappointment to Kanye that Kris, Kourtney and Khloé didn’t attend his fashion show,” a source told People Magazine.

“Both Kim and Kanye would have wanted the rest of her family in N.Y.C., too.”

Great news, though! Toolbag extraordinaire Jonathan Cheban showed his support!

Preparations for the show have reportedly taken a toll on West, who is also in the middle of his Saint Pablo tour, which kicked off August 25th.

“Kanye has been very stressed about his fashion show,” the source added.

“He is a perfectionist and was a nightmare before the show.”

And as many know, when one half of a couple is stressed and cranky, the other half gets the worst of it.

“Kim has definitely been annoyed. She is hoping that he will calm down now after the fashion show is over.”

Reviews of the show were not kind.  WWD wrote that “Adidas should be embarrassed” to be associated with the collection, but at the end of the day, it’s our own fall for encouraging West’s artistic endeavors.

“To a great extent, fashion and the press have only ourselves to blame,” Jessica Iredale wrote.

“We’ve been world-class enablers of Kanye West, allowing him to put us at his mercy.”

Radar Online claims that the family didn’t want to be involved in Kim and Kanye’s circus (which I find hard to believe, since the Kardashians love a good media circus).

“Kourtney cannot stand the drama anymore and she refused to go because she needed a break from Kim and Kanye,” a source allegedly told the site.

“She wanted to stay as far away from that mess as possible and she did not want her kids there either.”

Even Kris could not stomach another West production!”

That…does not sound like Kris Jenner.

As for Khloe and Rob?  The source said “they wanted no part of it.”

Maybe schedules just conflicted and the whole family couldn’t get together this one week in September?

It’s an insane theory, but I’m sticking with it.
