The 19-year-old was the picture of subtly sexy elegance in her high neck, mermaid green dress that fell to the floor and looked perfect on her slender model physique. The perfect Calvin Klein clothes horse indeed.
But while the custom-designed gown, created for her by Calvin Klein head designer Francisco Costa, looked demure from the front, it was a whole different story from the side.
When Kendall turned for the cameras on the star-studded red carpet in New York, the model-of-the-moment revealed the daring caged strands making up the side of her frock to reveal some serious side-boob. Hot mama!
Wearing her hair down, shiny and dead straight and parted in the centre, Kendall kept her makeup fresh and dewy, working flicky false lashes, a hint of peachy blush and a glossy pink lip. Gorgeous.
They made be sisters, but they were rocking two totally different looks last night…
Once inside, the reality TV star-turned-model got busy posing for bathroom selfies with her best gal pals, Gigi Hadid, Cara Delevingne, Hailey Baldwin and Joan Smalls.
And she was also spotted cosying up to her designer BFF Olivier Rousteing backstage for a sultry close-up selfie.
‘Secrets? @olivier_rousteing’, she wrote.
Meanwhile, sister Kylie Jenner may not have made the red carpet cut, but she made up for it in spades for the after-party.
While Kendall had changed into a red hot pencil skirt and silver sequin crop top, Kylie worked her signature street style cool in the sea of designer dresses, standing out in a pair of denim cut-off shorts, a black mesh Moschino crop top, a duster coat and heels.
‘Too much sexiness around me’, Kylie captioned their after-party shot.
Who needs the real thing when the after-party is this cool, eh Kylie?
