Allison Williams In L'Wren Scott - 2013 CNN Heroes  An All Star Tribute

Allison Williams attended the 2013 CNN Heroes: An All Star Tribute held at the American Museum of Natural History in New York City yesterday evening.

The ‘Girls’ actress opted for a super-sexy look, wearing a purple lacquer signature tweed dress from L’Wren Scott’s Spring 2014 collection.

Her dress, which sits just off the shoulder, was styled sans the Asia-inspired accessories we saw on the runway; Allison kept it simple with gold jewels and black pointy patent-leather Giuseppe Zanotti pumps.

I know some don’t favour this calf length, but I can find no faults with this ladylike look with a touch of sass appeal.
