Over the weekend, the Kardashian ladies attended Kris Jenner's annual Christmas Eve party.
Kim, Khloé, Kourtney, Kendall and Kylie all dressed up in gorgeous cocktail outfits and the whole family enjoyed an extravagant evening together.
Kylie Jenner rocked a black, sparkly jumpsuit and posted several photos on Instagram of her showing it off.
Look at that back view, god damnnnnn.
Look at this blurry pic of her touching Tyga, god damnnnnn.
Look at this Snapchat story of her staring at herself and making kissy faces at the camera.
The outfit is on point and perfect for the holiday season, except there's one teeny, tiny problem.
She totally stole it from Taylor Swift.
Yup, the "Shake It Off" singer wore the glittery jumpsuit to the 2016 iHeartRadio Music Awards in April.
LOOK, THERE'S PHOTOS TO PROVE IT.
In the clip below, you can even see them hug (TEEHEE) when Taylor Swift won her Album Of The Year award.
Taylor Swift decided to wear the jumpsuit with straight short hair and bangs, while Kylie partnered it with long, loose curls.
At the party, the rest of the Kardashians looked just as beautiful as Kylie, wearing gold, sparkles and fur.
We didn't forget about you, Kendall! Looking stunning, as always.
The Kardashians posted several photos from their night on Instagram, so you should definitely check these out for some New Year's Eve outfit inspiration.
Happy holidays, everyone! Before you go, let us know who you think wore the sparkly jumpsuit best. Was it Kylie Jenner or Taylor Swift?
May the best celebrity win!
