At last year's KarJenner's Christmas Eve bash — a ritual that began in 1978 — Kendall opted for a black-and-white mid-length dress with a white fur-like detail across the bodice.

For the holiday, Lopez wore her hair pulled back, but we know she's currently rocking an Old Hollywood–style lob, which stylist Rob Zangardi debuted just ahead of the holidays. Red-hot!

Prince Louis' outing at the Christmas carol concert was likely especially meaningful for Princess Kate, as her whole family was there to support her in hosting the holiday event during its third year.
