The Keeping Up With The Kardashians star gave us all an eyeful as she schmoozed with pals in this tiny, see-through lace bralet in which her nipples (and her nipple piercing - ouch!) were totally visible.
But it wasn't a cheeky, sneaky photographer that caught Kenny and her bare boobs on camera. In fact, it was her younger sister and Lip Kit founder Kylie Jenner who shared Kendall's assets with the world - via the medium of Snapchat, obviously!
Kylie snapped a five second clip of her sister talking with a friend and zoomed in on the eye-wateringly tiny cropped top which Kendall teamed with a high-waisted pair of shorts, sandals and a wide-brimmed hat.
Kendall also took to Instagram to show off her transparent top, and shared a series of saucy snaps with her fans and followers. You've got to admire her confidence...
That said, when Kendall decided to head home from the festival she covered right up in this 90s-inspired sporty red tracksuit - a far cry from the non-existent ensembles she sported alongside her sister, Vanessa Hudgens and Millie Mackintosh to name but a few celebs also in attendance.
You can't be a show off all the time, eh?
