Kourtney Kardashian Heats Up Instagram In Revealing High-Cut Bodysuit From SKIMS

Kourtney Kardashian took to Instagram Tuesday night to show off her curves in a sexy yet casual outfit. The Keeping Up With The Kardashians star shared three photos of herself rocking a skintight bodysuit from her sister, Kim Kardashian's SKIMS line. Check it out below!

The 42-year-old Posh founder rocked a plain black one-piece that tightly hugged her torso. It featured short sleeves and a round neckline, showing a hint of her collarbone. The lower part was pretty high-cut, displaying her bare hips and flawless bikini line. From what was visible, Kourtney went braless under the skintight piece, but the dark color helped in obscuring the necessary bits.

The first frame captured Kourtney from the front as she looked straight into the camera with her head tilted and lips parted. She popped her hip to the side, placing her left arm over her thigh, while the other arm stayed behind her backside. The image was cropped at her thighs, giving her fans a nice look at the details on her bodysuit. Her hair fell over her right shoulder with a few strands falling on her face, covering some parts of her eye.

A swipe to the right showed more of the reality star's body. This time, the photographer included her legs in the shot. Kourtney's left hand was on her waist as she pushed her hip sideways and gazed at the lens, showcasing a fierce look.

The mother of three was photographed at a closer angle in the third photo. She spiced things up by tugging at the sides of her bodysuit and giving a tantalizing stare.

Kourtney rocked a full glam look for the photoshoot that included black mascara, darkened eyebrows, a smoky eyeshadow, blush, highlighter, and nude lipstick with a sheen finish. For the occasion, her long black hair was styled in loose waves and her nails were painted with a bright green polish.

Kourtney tagged the loungewear brand in the caption after dropping a black heart emoji. She also gave credit to her glam team and photographer by tagging their Instagram accounts on the first picture.

As per usual, Kourtney's fans flocked to the comments section underneath the photos to show their support for her. The post — which she shared with her 144 million Instagram followers -- garnered about 1.3 million likes in under a day since being posted. In addition, the same time period also brought in upwards of 6,000 comments from gushing admirers.

A fan told Kourtney that she's the "MOST interesting to look at."

"Def proved Kim saying you're the least interesting to look at wrong with this ad campaign," echoed another follower.

Meanwhile, a third admirer noted that Kourtney is "everybody's favorite Kardashian."

"So beautiful with such perfect b**bs," added a fourth one.

A few days ago, the 40-year-old SKIMS founder went a trip down memory lane by sharing several pics of her teenage self, along with a story about the night she got grounded. Now, the little revelation involved Kourtney. Kim claimed that her older sister stole their mom, Kris Jenner's "car just to drive it around the block." Kim also noted that Kourtney and her friends "were such bad influences."

Yesterday, Kourtney clapped back at Kim by sharing a Peppa Pig meme about the beauty mogul's diamond earring dilemma. While some fans think that the posts sparked a little argument between the two, it really didn't, as Kourtney chose to promote her sister's brand, as seen on her latest share.
