The two Jenner sisters coordinated in white looks, with the makeup mogul sporting a sequined Saint Laurent gown and the model in a silk Phoebe Philo gown.

In photos shared to her Instagram Story, Jenner looked elegant in a silky white dress. From the front, the dress channeled old-school sophistication with its high turtleneck and billowing long sleeves. But, from the back, there was a hint of sultry playfulness due to the gaping backless design, which was accented by a long tied sash.

Kendall Jenner saved her most elegant fashion moment for the holidays. The model attended the Kardashian-Jenner annual Christmas Eve party, wearing a fitted long-sleeve gown from Phoebe Philo. Jenner had her hair styled down in curls and accessorized minimally.
