"Kendall copied me on my dress," Kylie said on her Instagram page.

At the party, the three sisters hung out with friend Shamari Maurice and shared holiday pics that appears to have been taken at a photo booth, which featured the message, "Better Not Pout!!! Love, the Jenners and Kardashians 2014, Merry Christmas."
