Kylie Jenner is getting into the holiday spirit! The beauty mogul stepped out to attend a Valentine's Day party on Wednesday night, dressing head-to-toe in red for the themed bash. Kylie, 22, donned a bold red Body By Raven Tracy ensemble to her pal Stassie Karanikolaou's holiday bash, held in Beverly Hills. The Keeping Up With the Kardashians star paired the look with a Judith Leiber lips purse.

Kylie posted a few photos of her outfit on Instagram, writing, "someone said there was a vday party♥️♥️♥️."

The star-studded guest list also included Kylie's brother, Brody Jenner, as well as Chris Brown, Diplo, French Montana, Madison Beer and Olivia Jade.

"Kylie arrived at about 11:30 p.m. Most guests had already arrived at that point," a source tells E! News. "She wore a red jumpsuit with her hair pulled back, she looked great."

"They kept it pretty calm and didn't play music loud," the insider continues. "There were probably close to 100 people there."
