Kylie, 18, proved she could give her older sister a run for her money in the modelling world as she paraded her incredible curves in a canary yellow bikini.

Featuring a risque front clip, the skimpy top showed off her ample cleavage and complemented her tanned and toned complexion.

Donning a pair of matching bottoms with an elasticated black double waistband, the starlet also flaunted her famously perky posterior as she stretched out on the sand. 

Kylie enhanced her flawless features with a sweep of rouge across her defined cheekbones and slick of nude lipstick on her plump pout. Contoured to perfection, the starlet dazzled on the shoot 

Looking every inch the supermodel, Kendall, 20, showed off her phenomenal figure in a sporty white two-piece which clung to her athletic physique

Flaunting her incredible figure in the scanty swimwear, Kendall proved her model credentials as she posed up a storm, running her fingers through her locks and arching her back for the camera
