Kourtney Kardashian looks ready to party in black ‘sparkle pants’ ahead of a night with her sisters

Her youngest sister Kylie Jenner declared ‘the bands back together’ in a celebratory Instagram post.

And Kourtney Kardashian looked like a rockstar as she showed off her outfit on Friday night, which she wore ahead of a recent night on the town with her sisters Kim and Khloé Kardashian and Kendall and Kylie Jenner.

The 41-year-old Keeping Up With The Kardashians star lit up the evening thanks to a sparkling pair of black sequined slacks.

Time to party: Kourtney Kardashian, 41, looked stylish and festive in black sequined pants ahead of a night out on Friday with her sisters

Kourtney shared several photos of herself strutting in her pristine look down a hallway in her home.

She showed off a bit of her toned tummy thanks to her white cropped tank top. 

The thin article of clothing didn’t leave much to the imagination, as her black bra was clearly visible underneath it.

She matched her undergarment with a striking set of gleaming high-waisted trousers decked out in sequins.

The pants got some extra intrigue thanks to the shredded pant legs, which turned into fringe that reached down to the ground.

Kourtney wore the look with a pair of black open-toe platform heels, both to add to her 5ft1in stature and to keep her from tripping over her pants.

She departed from the standard Kardashian–Jenner clan middle part and instead parted her raven locks at the side and swept her navel-length hair over one shoulder.

In addition to her action poses, the Poosh founder snapped a picture of herself surrounded by shoes in her enormous walk-in closet as she got ready for an evening out.

‘Sparkly pants,’ she simply captioned her post.

In a follow-up post from later in the evening, Kourtney showed herself sitting to reveal that her pants only had a revealing lattice-structure beneath the thighs, which was covered by the fringe when she stood up.

She sat on her younger sister Khloé’s lap on a beige sofa next to Kim, Kylie and Kendall.

Kourtney stared seductively into the camera with her hair arrange in Veronica Lake–style peekaboo locks over one eye.

Kourtney looked serious and refined, while Kim was in a playful mood with her tongue out and her middle finger up, which Kylie and Kendall mirrored.

‘Where’s Rob?’ she joked in her caption, referring to her shy brother Rob Kardashian, who regularly stays away from public outings.

Her sister’s shared other fun variations, including one photo of Kim flipping the bird high in the air, while Kourtney was all alone as she gave the camera the middle finger in another snap.

Khloé was dressed in a striking blue patterned bodysuit, while Kim wore a maroon mini dress and thigh-high beige suede boots.

Kylie stunned in a black halter dress with a cut-out section highlighting her cleavage, while Kendall showed off her lithe figure in a brown tube top and leather pants with brown snake-print boots. 

The sisters didn’t reveal their recent evening destination, but Kim posted video from her night out on Friday, which showed her trying to pilot a Lamborghini that appeared to be unfamiliar to her.

While she was in the car with her former assistant Stephanie Shepherd, her family friend Jonathan ‘Foodgod’ Cheban’ drove by in his own sports car, so she called out to him and decided to follow his vehicle.

Sitting out the evening were Kourtney’s three children: Mason, 11, Penelope, eight, and Reign, six.

She shares all three with her former partner Scott Disick, 37, who declares his love for her years after their separation in a teaser for the upcoming episode of KUWTK.

Despite the declaration, Scott later moved on with Lisa Rinna’s daughter Amelia Hamlin, 19.
