Photos: Kourtney & Khloe Kardashian step out in stylish but racy dresses at a fundraising event in New York

Kourtney and Khloe Kardashian walked the red carpet at the Angel Ball - a charity event in New York on Monday. Mother-of-three Kourtney wore a black dress which featured a cutaway skirt that displayed her toned thighs, while Khloe stepped out in a nude sheer gown, which was covered in silver and diamond detailing.

Their late father Robert Kardashian, who died of esophageal cancer in 2003, was being honored at the Ball, which was held at the Wall Street branch of upscale restaurant Cipriani. The annual event raises money for the Gabrielle’s Angel Foundation for Cancer Research and the Kardashian sisters presented a cheque for $250,000 to the foundation from the Kardashian and Jenner family.

Kim K had been slated to make her first appearance on the red carpet since her ordeal in Paris, where she was allegedly robbed at gunpoint in June. However she pulled out of the engagement following her husband Kanye's hospitalisation.
