Kim was spotted as she climbed out of her car ahead of a slap-up lunch and was showing off her curvaceous figure in an all-white ensemble.
The mum-of-one had teamed a very tight long skirt (what's new?!) with a white crop top, allowing her to flash the tiniest bit of flesh.
Kim then topped off her outfit with nude sandals and a cosy cream jacket to keep off the chill, before sweeping her hair into a low ponytail.
On Tuesday, Kim's stepdad Bruce turned 65 and he marked the occasion with a lunch for the family at his beach house in Malibu.
Kim has since shared several photographs of the celebrations with fans on Instagram, and one of which shows her sat alongside Bruce and her four sisters at the table.
Bruce looks seriously chuffed to be surrounded by his favourite beauties - Kim, Kourtney, Khloe, Kendall and Kylie - and Kim commented on the snap: "Family lunch #Bruce'sBDay #Malibu."
She also posted a picture of herself, Bruce and youngest sister Kylie, adding: "#Family #MalibuDayz."
It looks like Bruce had a great birthday and he even celebrated by visiting the nail salon for a red polish manicure...
The former Olympian did, however, keep his fists clenched during the photos and it is thought he had removed the nail varnish before the lunch anyway.
It has since been reported that Bruce only got the beauty treatment done as a joke, amid rumours he is transitioning into a woman.
