'So vintage': Disco-babe Kendall Jenner looks ready for Studio 54 in a sparkling throwback costume

Halloween is only a couple of days off.

And Kendall Jenner was in the spirit of the season on Sunday, ready to play dress up and post the result to Instagram .

The 21-year-old looked up the route to Studio 54 in the late 1970s, wearing a sparkling pair of cat-eye sunglasses and matching long gloves.

Her neckline fell to her midriff, and she tucked her cleavage-baring white top into a high-waisted pair of royal purple shorts.

Kendall had got herself a blazer in the same shade of purple as her shorts, flinging it casually over one shoulder and holding it in place with her fingers.

She rounded off the look with a glistening pair of drop earrings, plus a black-and-white striped hat with an asymmetric brim.

Instagram, Kendall modeled out and twirled about, giving the camera a scarlet-lipsticked smile.

She wrote in her caption: 'so vintage.'

Kendall tagged stylist Marni Senofonte, who famously also worked with Beyonce on Lemonade; Jen Atkin, the coiffeuse Kendall's whole family turn to; and makeup man Rob Scheppy, who also works with the Kardashians and Jenners.

Meanwhile, Kendall's little sister Kylie Jenner, who is rumored to be pregnant at 20 by her 25-year-old boyfriend Travis Scott, looked more casual on Sunday.

She posed on her Snapchat Story with her family's matriarch Kris Jenner. Mother and daughter both sported cartoon dog ears and snouts, courtesy a filter.

Before that, Kylie had spent a bit of time filming herself as she sat listening to the music in her Rolls-Royce, which appeared not to be moving.

The Life Of Kylie star veered the camera this way and that, pouting.

A cartoon string of streamers was draped over the frame near the bottom, just above the festive yellow text blaring that it was 'SUNDAY.'

Kylie had shown off her car - which is silver on the outside, with a black and blue interior - on Snapchat shortly beforehand.

It was open as it stood parked on a stone-tiled driveway.
