The event benefits Autism Speaks and was held at the Grand Hyatt Hotel in New York City.
The twins took some time to work the red carpet, even stopping to pose with Steve Madden.
As for their outfits, they both went with the vintage choice, with MK wearing some Proenza Schouler heels and Ashley in Azzedine Alaia heels.
What do U think of their outfit choices? A hit or another miss?
