Putting on a flawless display, the American actress slipped into a form fitted dress which featured long lace sleeves.

Chastain allowed her hair to graze her shoulders as her flamed-coloured locks dropped in loose curls styled in a side parting.

Meanwhile, Jessica was recently in Canada to promote her latest film The Martian as part of the 2015 edition of the Toronto International Film Festival.

Stealing the attention away from her co-stars at the premiere last Friday, the Zero Dark Thirty actress looked amazing in a midnight blue velvet dress.

Rocking colour coordinated heeled sandals, Chastain finished her red carpet look with crimson lipstick perfectly matched to her manicure.
