Not to be outdone by her celebrity guests, the model and KUWTK star decided to rope in pals Hailey Baldwin and Justine Skye to dress up as the X-rated version of the Powerpuff Girls.
Kendall transformed the usually tomboy character Buttercup into an all-out dominatrix, complete with a spiked collar, fishnet stockings, tattered black miniskirt, green bra, and thigh high boots.
Meanwhile, Hailey made the usually sweet and charming Bubbles a little less so in a blue and black mini skirt and cropped top and matching choker.
And singer/model Justine gave new character Blisstina a proper introduction in a purple and black leather getup and a long blue wig accessorized with a pink heart.
Elsewhere at the party were Halsey and G-Eazy, who went as the legendary Princess Leia and Han Solo. Halsey’s sexy outfit was just barely holding on by a thin thread!
And singer/actress Tinashe was sinfully hot as a red devil donning red horns, red lipstick, red wig, and a red bustier with red leather boots.
Clearly everyone who’s anyone RSVPed for this, except new beau Blake Griffin, who didn’t appear to be among the crowd.
