The Keeping Up With The Kardashians sisters are famous for their fancy designer wardrobes, and they looked as fab as ever while promoting their new action-packed book, Rebels: City of Indra: The Story of Lex and Livia.
Model Kendall opted for a sophisticated vibe, showing off her figure in a form-fitting pencil skirt complete with a black mesh overlay.
The stylista also rocked a dangerously low-cut navy bustier, topping her chic ensemble with an elegant pair of pointed heels.
Meanwhile Kylie went for monochrome for the occasion, sporting a simple striped dress with an asymmetric hemline.
She added a rock chick edge by layering up with a leather biker jacket while donning a pretty eye-catching pair of lace-up heels.
And of course Kylie didn't go unnoticed in the hair department, styling her blue dip-dye locks in a straight and sleek blunt 'do.
The gorgeous starlet flaunted feline winged liner paired with a rosy nude pout, while Kendall smoked out her peepers with forest green eyeshadow, finishing with dusky pink blusher and a slick of pearlescent lippy.
Looking fab, ladies!
