The Keeping Up With the Kardashians star dialled up the sex-factor and turned heads as she slipped into this v-e-r-y revealing, spray on leather dress that boasted a rather precarious criss-cross front, giving us an eyeful of her boobs!
Thankfully mum-of-two Kim managed to avoid an embarrassing nip slip (probably thanks to her failsafe duct tape trick - ouch) as she posed up a storm next to Kourt who looked super-sleek in a slinky off-white top and a matching studded mini skirt.
All eyes were on Kim's racy, bondage-inspired frock which she teamed with a 90s-inpired choker, her trademark strappy sandals and poker-straight tresses, but her barely there make-up was a winner, too!
Kim glowed under the camera flashes thanks to a heavy dusting of highlighter and she swapped matte lips for a slick of plumping gloss.
The reality beauty - also joined by new mum Chrissy Teigen - took to Snapchat to give us a glimpse of the bash in full swing and there was a whole 'loada pouting, posing and twirling going on.
If you've got it, flaunt it. Right?
