The Keeping Up With The Kardashians star showed off her figure on the runway as part of New York Fashion Week in a sheer top and cropped trousers ensemble.
The revealing light brown v-neck top was teamed with two-toned beige and brown cropped trousers, tights and boots, along with a stylish bag.
Kendall, 18, looked almost unrecognisable in a sharp bobbed wig and headband and powdered-out eyebrows.
Her proud big sister Khloe Kardashian posted a series of snaps of Kendall’s appearance at New York Fashion Week on Instagram.
"My baby sister killed it today walking in the Marc Jacobs fashion show!!! Kenny you are so dope to me!!! Congrats my baby!!! #NYFW #MarcJacobs #ProudSis," wrote her half-sister.
Kim Kardashian shared another touching message on the picture-sharing site: "Proudest sister ever!!!! I love watching you live your dream!"
Kendall began her modelling career at 14 years old when she signed up to the Wilhelmina agency.
In November last year the teenager signed up to prestigious new modelling agency The Society Management – which represents Victoria's Secret Angel Adriana Lima.
