The Keeping Up With The Kardashians star looked absolutely sensational at the star studded bash and she put a high-fashion twist on the classic little black dress.
The model of the moment - who is also the face of Estee Lauder - proved that she can pull off anything and everything as she slipped into this eye-catching asymmetric number which boasted a skin-tight Bardot-inspired top, a sequin splashed neckline and an elaborately embellished skirt with a killer side-split.
HELLO, leg envy.
Reality babe Kendall was all smiles as she sauntered through Selfridges' world-famous beauty hall in a pair of matching pointed court heels. The starlet scooped her hair up into a fuss-free, high ponytail but it was her incredibly f-l-a-w-l-e-s-s make-up that really stole the show.
KJ - who recently dazzled in a series of stunning gowns at Cannes Film Festival alongside mum Kris and Scott Disick - gave her trademark nudes the elbow and stood out thanks to a slick of tomato red lippie that accentuated her gleaming, dewy skin.
After signing autographs and posing up a storm for the paparazzi, Kenny schmoozed with Little Mix's Leigh-Anne Pinnock, Made In Chelsea's JP and Vogue Williams to name but a few celebrity guests also in attendance.
What a night.
