Kim Kardashian & mom Kris Jenner pose in matching black outfits as she quotes line from Pretty Woman

Kim Kardashian was active on social media on Saturday when she took to Instagram to share a new post with her mom Kris Jenner.

The 42-year-old media personality and the Kardashian/Jenner matriarch were decked out in sleek black outfits.

The mother-of-four quoted a famous Julia Roberts line from the 1990 film Pretty Woman when she wrote in her caption: “Big mistake.” Big. Enormous.’

The SKKN by Kim founder was dressed in a skintight high-neck textured jumpsuit as she posed in front of the clothing racks.

And her manager mother was equally fashionable in a smart tuxedo with structured shoulder pads.

Kim wore her sleek raven locks in a high, straight ponytail that was pulled on top of her head and flowed down her back.

She flaunted diamond earrings and a face full of glamorous makeup in the snaps.

Kris’s second daughter, Kim, played up her thick brows and contoured her cheeks before finishing with a bright pink lip stain.

Kris, for her part, sported her signature short haircut, diamond earrings, and a full face of makeup.

Her business-ready gown featured white-piped cuffs and striking silver buttons along the front of her gown.

One photo was clear and taken digitally, while the second was more grainy, like it was taken on film.

The duo appeared to be in some sort of retail store as racks of black clothing hung in the background.

The quote was from a scene in the film in which Julia’s character, Vivian Ward, is turned away from a luxury store by two presumptuous sales clerks.

Later, Vivian returns to the establishment with her hands full of shopping bags as she tells the women that they made a “big mistake”.

It comes shortly after Kim and her younger sister, Kylie Jenner, 25, spent some quality time together at a SZA concert.

The two Keeping Up With the Kardashians stars bonded backstage, where they danced to one of the musical artist’s songs, Snooze, while playing golf indoors.

In a video posted to the SKIMS founder’s TikTok account, the two moguls had fun together as the song from SZA’s latest album, SOS, played.

Kardashian donned a body-hugging black and white crocodile pattern jumpsuit with a high neckline.

She paired the look with light gray heeled ankle boots and wore her brown hair in waves that flowed to her shoulders.

Kylie flaunted her style as she modeled a loose fitting white tank top underneath a cream strapless corset.

The mother-of-two styled the top with matching cream opera gloves, leather pants, and a pair of white heeled boots.

Accessorized with black sunglasses and a small black bag, the beauty also wore her long dark hair down.

The socialites lip-synced to the song as they moved around each other, playing with the camera and showing off their figures.

In a recent interview with vanity fair italyKylie revealed that Kim is currently her favorite sister in the Kardashian/Jenner clan.

‘It changes over time. Right now, it’s Kim,’ she shared. ‘Kim has changed a lot recently.

We are very connected. She is always the first sister I call when I need something. We have been going through many similar experiences lately.

The Kylie Cosmetics founder then added that each of her sisters brings a different kind of value to her life.

‘Khloé taught me tenderness and the ability to forgive; Kendall, the importance of friendship and unconditional love; Kourtney, the value of health and the need to not be superficial; Kim, the strength and ability to always tell yourself that you can do it, no matter what. Kim is really strong, really resilient.’
