Jessica Chastain opted for a simple and elegant look at the
24th amfAR Gala Cannes in Antibes, France on Thursday (25.05.17).
The 40-year-old actress dazzled in a black backless gown which clung to her admirable figure and flared out into a floor length skirt.
The star completed her look with a classy necklace and coral-coloured nail varnish.
