Jessica Chastain in Herve L. Leroux | “Lawless” Photocall – 2012 Cannes Film Festival

Jessica Chastain has been very busy during the Cannes Film Festival this year; after heavily promoting “Madagascar 3″ the past two days, she’s now moved onto her second film “Lawless”.

The 35-year-old actress joined her costar Mia Wasikowska this afternoon for the photocall and press conference.

Jessica wore a black  v-neck pencil dress — from the Fall 2012 collection by Herve L. Leroux — with multicolored stripes throughout the bodice and a strappy open back.

The dress fit her really fell, and I love the way the hues of the red in the printed design popped against her light red hair.

Speaking of her hair — I love the sweet braid she had going on today!

Jessica finished off with black patent slingback, double platform Giuseppe Zanotti pumps with tiger printed calf-hair heels.

What have you thought of Jessica’s Cannes looks so far?
