The Kardashians were their usual glam selves Christmas Eve at Kris Jenner 's annual party. But on social media, they shared Christmas Day throwback pictures that featured decidedly less sparkles.

According to a tweet from Khloe Kardashian , the family has an annual tradition of wearing matching Christmas pajamas. Her Instagram gave a small glimpse into this year's pattern with pictures of her and nieces and nephew North, Penelope and Mason.
