Kourtney Kardashian's look for the family's Christmas Eve gathering was a total 'sleigh,' as seen in pics shared by her sister Kim Kardashian.

The Blink 182 drummer and his wife of over two years were joined by the three children Kourtney Kardashian shares with Scott Disick — Mason, Penelope and Reign — as well as Travis Barker’s son Landon, who he shares with Shanna Moakler, and Atiana De La Hoya, Moakler’s daughter with Oscar De La Hoya.

Guess this is Kim Kardashian’s version of casual. After the Skims founder, 44, told Vogue that the famous family would forgo their annual over-the-top party in favor of a “really low-key” Christmas Eve party, she got all dressed up in a skin-tight gown.
