Kim Kardashian Joined Her Sisters at a Magazine Party, but Kylie Jenner Didn't Get the "Wear All Black Email"

KUWTK stars celebrated the magazine's 50th birthday

It was a night out for some of the Kardashian women!

Kris Jenner, Kourtney Kardashian, Khloé Kardashian and pregnant Kim Kardashian took a magazine party by storm Monday night, making bold statements in their daring ensembles. The women stunned on the red carpet in their all-black ensembles, except it looks like Kylie missed an important message because she's the only one not wearing black.

She noticed her family faux pas, too, and took to Instagram to call herself out for wearing white when everyone else went with the opposite. "I didn't get the 'wear all black' email," she wrote alongside a group shot.

As they say, dare to be different, Kylie!

The 18-year-old star looked gorgeous in a thigh-skimming, cream-colored dress, while the rest of the group wore a combination of floor-length black dresses and jumpsuits. Kim, who is almost two months away from her expected due date, put her baby bump—and lady lumps—on display in a skin-tight black dress that landed just above her ankles. 

All six of the Kardashian-Jenner women, including Kendall Jenner who was noticeably absent from the soiree, were featured on the magazine's cover, which was the first time in four years they all appeared together for the same photo shoot.

The special issue dedicates 16 pages to "America's First Family," which received plenty of backlash. Many readers did not appreciate the Keeping Up With the Kardashians stars being compared to the Obamas.

Don't forget to tune-in to the season 11 premiere of Keeping Up With the Kardashians on Nov. 15 at 8 p.m. only on E!.
