Khloe and Kourtney Kardashian were positively angelic-looking on the 2016 Angel Ball red carpet in New York City on Monday, November 21.

The Kardashian sisters (minus Kim, who is currently tending to her husband Kanye West following his reported hospitalization in Los Angeles) hit the gala event in their finest haute couture, with Khloe wearing a shimmering silver gown from Kuwaiti designer Yousef Al-Jasmi, while Kourtney stunned in a classic black ruffle gown featuring nude cutouts.

Along with their mom, Kris Jenner, Khloe and Kourtney were on hand to honor their late father, Robert Kardashian, who passed away from esophageal cancer in 2003, as well as donate $250,000 to benefit lifesaving cancer research.
