Kylie Jenner lit up like a Christmas ornament … stepping out in a jaw-dropping, figure-hugging fire engine red dress that had every head swiveling.

The mogul rolled up to the OBB Media holiday party in West Hollywood Saturday night, looking like the gift that unwraps itself, serving major festive glam as she slipped into the event.

The glossy, curve-clinging gown hugged every angle as Kylie made a grand entrance, instantly becoming the unofficial centerpiece of the party that kept the room buzzing.
