She complemented the sexy number with a pair of nude, backless heels with perspex straps.
The mother-of-two’s bouncy brunette locks were arranged in a center part and fluffy barrel curls.
And the makeup mogul’s visage was beautifully made up, with her cheeks blushed and her pout coated in a mauve lipstick with darker liner.
For her part, Kendall wowed in a layered, straight-cut top and matching teeny skirt.
She punctuated the simple and sophisticated outfit with strappy black heels.
The runway regular wore her dark hair loose, also style in a middle part as it flowed down her back.

This week Kendall opened up to Vogue about the dynamic between her and Kylie, whose parents are Kris Jenner and Caitlin (nee Bruce) Jenner.
‘Even with my little sister — the biggest thing we would fight over was the TV remote. There was never that who’s-better-dressed, who’s-prettier thing. It was always: You’re you, I’m me,’ she told the fashion magazine.
‘I’ve never thought of my career as a competition, and that’s thanks to awesome sisters. I really do me, and if you don’t like it, that’s okay. But I trust that me being the most authentic version of myself will get me to the places it needs to get me,’ she added.
Kendall and Kylie launched their careers as teenagers with Kendall + Kylie collaborations with PacSun, Topshop, Gillette, Steve Madden, Pascal Mouawad’s Glamhouse, and Glu Mobile.
