Girls actress Allison Williams was attending the Elton John AIDS Benefit in New York yesterday. She wore an amazing Dior couture dress to the event. It featured a halter neck and two long sash details at the back. She looked absolutely stunning.

The front looked great. The back looked great. The ponytail was super GREAT. Those earrings — also by Dior from the fine jewellery range — were perfectly great. I can't fault anything at all about this look. It is a winner. Very nice indeed.
