Allison Williams In Sachin + Babi - Barneys New York Celebrates Irene Neuwirth

Mark Lee, Barneys New York CEO, hosted a dinner party to celebrate jewelry designer Irene Neuwirth yesterday evening in New York City.

Allison Williams, who continues to be the most in-demand star on the red carpet at the moment, was in attendance wearing a Sachin + Babi Fall 2012 dress.

Perhaps inspired by the runway, the actress styled her metallic-grey-and-black leather peplum dress with black pumps.

I wish that she’d also taken a cue from the runway and added a belt to her look.

I should be drooling over her stunning Irene Neuwirth fire-opal earrings, but I’m too busy missing that waist-defining belt.
