Kendall Jenner – the youngest Kardashian who announced her alliance with Estee Lauder back in November –  is sporting leather pants on the catwalk in a video that marks her first gig as the face of the brand.

Jenner is promoting Estee Lauder’s new Little Black Primer, a lash primer that claims to boost the lashes’ volume and length. It can be used before applying mascara – or, alone for a fresh-faced no-makeup look, which Jenner sports so well. The brush features bristles with a deep curved arch, resembling a half-moon shape.

The reality star/fashion model debuted a clip from the video on Instagram, and racked up 220k likes in 2 hours.
