The Kardashians-Jenners are having a Christmas party for all of their businesses

It's the season, and the Kardashians threw a lavish Christmas party at the workplace to toast a year of success, just like your office does. Well, maybe a little more lavish than yours.

The celebration took place Tuesday night at the family's longtime restaurant, Casa Vega... and Kylie Jenner made sure we got a glimpse of all their decorations and, of course, a great look at her form for the night.

The party was meant to honor the Kardashian-Jenner business empire...partly comprised of Kim Kardashian's SKIMS shapewear collection, Kylie's makeup line, Khloe Kardashian's Good American line and Kendall Jenner's 818 Tequila.

Mama Kris made sure to thank her daughters...as she bragged about their thriving businesses.

It felt like a really good turnout...not just for the family, but for everyone working behind the scenes on their various teams, including Kim's longtime friend and brand manager in his company, Tracy Romulus.

All the guests were in attendance, beyond the open bar, as the family prepared huge goody bags filled with plenty of goodies, including items from Kim's SKIMS range.
