King Kylie Jenner‘s court came out in full to support her cosmetics pop-up Friday night … with her sisters leading the charge.

The reality star and mogul — who recently embraced her “King Kylie” persona while featured on Terror Jr.’s song “Fourth Strike” — held the event in L.A. … and, she hopped out of a car looking Barbie Chic and holdings hands with her daughter Stormi.

KJ showed off her curves in a bright pink latex dress and a matching pink wig … really putting the HOT in hot pink.

Her sisters Kim and Khloé Kardashian followed her out of the whip … each in barely-there outfits of their own.

Hailey Bieber went a bit off theme in an alluring black gown … but, she was still the life of the party — taking pics with Kendall Jenner who added a splash of blue to the festivities.

Among the others in attendance … Kris Jenner, Corey Gamble, Alabama Barker and even Jessie and D’Lila Combs — Diddy‘s twin daughters — who wore their standard matching outfits.

As you know … Kylie’s selling a “King Kylie” collection of makeup — a throwback to her mid-2010s alter ego. She built an empire on bold colors and wild hair — which perfectly describes last night’s outlet.
