Every warrior princess needs her warrior and Kylie Jenner wasn't disappointed as Tyga fully embraced the couples costume choice. Kylie's glamorous look included 40 inch hair extensions and a body baring bra top. She wore a skirt with thigh high splits as was surrounded by her ninja crew. E J Johnson stood out from the crowd in a red suited cabaret look, a top hat and smoky eye make up adding plenty of drama.Sofia Richie was straight out a slasher movie with a gash on her forehead while Paris Hilton went for the sexy option and flashed the flesh in an intergalactic leather two-piece. Kendall Jenner was of course at the bash hosted by her sister Kylie. The model turned to her Chanel's Karl Lagerfeld for some inspiration.
