Out for a night on the town, Kendall and Kylie Jenner attended the 2012 KIIS FM Jingle Ball in Los Angeles on Monday (December 3).

Dressed in a high-waist black leather mini and grey shoulderless sweater, Kendall posed for photos alongside her sister, who sported a black leather mini of her own and a black printed t-shirt for the music event.

The Jingle Ball is a two-night celebration of music. Saturday night was filled with performances by Taylor Swift and the Jonas Brothers, among others.

The final night will included Justin Bieber, Ke$sha, Flo Rida, and Psy hitting the stage.
