The image was taken in her bathroom in front of a towel rack and did not show her face.  

Beside her $32 asymmetrical bra and $14 barely-there thong, she wore a light brown nail polish and her dark locks back in a sleek updo. 

The reality star, who is a fixture in Vogue and has walked on runways across the globe, maintains her lean figure by frequenting high intensity workout classes, like kickboxing.

She also gets her steps in by walking her beloved Doberman, Pyro, and increased muscle strength by hitting Pilates classes with her best friends Bella Hadid or Hailey Bieber. 

Jenner is also said to eat ‘plenty of nutritious foods like lean proteins, veggies, and whole grains’ while limiting dairy and cheese, according to Healthline.
