The star-studded event featured an array of glamorous outfits, with Paris wearing a short red dress made of lace while singer and dancer Paula Abdul donned a see-through emerald green gown with glitzy sequin detail.
Model Heidi Klum also got into the festive spirit with a stunning white dress with a cut-out neckline that featured a gold chain wrapped around her neck.
Kim however stood out among the crowd after she rocked a surprisingly casual outfit compared to other attendees.
A snap shared on Instagram showed the star posing with Paris wearing a cropped dark t-shirt and black leather pants with black beaded panelling on the sides.
She kept her accessories to a minimum, wearing just a necklace with a cross pendant as well as a diamante choker.
Fans were shocked by the star's choice of outfit, with many taking to the comments to mock her.
"Everyone dressed all nice and Kim looks like a 15-year-old teen that was forced to her parents' party," one roasted the star on Instagram.
"Why is Kim dressed like that?" another questioned.
"Did Kim not understand the holiday party attire assignment?" a third added.
"Kim wore a horrible outfit to a holiday party," a follower commented while somebody else dubbed it "disgraceful".
It comes after Kim was slammed for a snap of her wearing a white see-through bikini with the caption, "Life tip – do you".
Her advice prompted an outpouring of snarky responses from people on social media.
“Despicable we don’t need life tips from you,” one person fired out.
“Kim, love ya but this caption is very 2012,” another added.
