1 Way Kylie Stood Out From the Kardashian-Jenner Crowd at Cosmo's Big Party

It's a rare occasion when the Kardashian-Jenners walk the red carpet together, but it seems last night "America's First Family" made an exception. Save for Kendall, who was most likely busy with modeling duties, the Keeping Up With the Kardashian ladies stepped out to celebrate Cosmopolitan magazine's 50th anniversary — the very publication that gave them the controversial "First Family" title.

While all black looks seemed to be this group's theme at the bash, Kylie stood out in the crowd wearing an off-white sweater dress. Later, the star turned to social media to joke about the contrasting look, saying she "didn't get the 'wear all black' email."

Regardless, the whole family looked pretty stunning. Scroll through to see their looks in full, then take a peek at their spread from Cosmo's November issue.

Kim opted for her usual uniform: a formfitting dress and a duster jacket of the same color, switching things up with a statement-making choker.

Kourtney went with a jumpsuit, which may have been a tad too long for the petite star.

Khloé couldn't help but show off her skin, going with both a deep V-neck cut and leg slit.

Kris looked cozy and superchic in a long-sleeved black jumpsuit.

Kylie, who didn't pose solo on the red carpet, blamed poor communication for rocking an off-white look, claiming she "didn't get the 'wear all black' email."
