January Jones in Jason Wu | The Cast Of “Mad Men” Rings The New York Stock Exchange Opening Bell

The cast of “Mad Men” continued to promote the fifth season of their hit series when they rang the opening bell at the New York Stock Exchange yesterday in NYC.

January Jones looked beautiful in a black and white brushstroke combo knee-length dress, from the Pre-Fall 2012 collection by Jason Wu, with black three-quarter sleeves and a waterfall asymmetric skirt.

This pretty design was broken up at the waist with a black leather belt.

January attempted to add a pop of color with her cool Spring 2012 color-block Prada pyramid tote, but she failed to capture the fun element that came with the emerald green cross-body carried by the model.

She completed her look with a scarlet red lip and a pair of strappy black “Vamp” suede sandals by Jimmy Choo.
