Kylie turned heads in a shimmery black sequin dress with a plunging neckline and a thigh-grazing split on one side which showcased her toned pins.
She posed for pictures with her sister Khloe Kardashian, 35, ahead of the bash which were later posted online.
Not to be outdone by her younger sister, TV personality Khloe, who wore her hair in a sleek blonde bob, was dressed in an even more eye-catching look.
The braless star sported a sparkly silver jacket with a pair of matching skin tight leggings for the occasion.
