The actresses both wowed fans as they graced the red carpet at the Critics' Choice Movie Awards last night in two show-stopping gowns.

While many of the famous attendees opted for the usual pallet of black, grey and white, Jessica and Amy brought a splash of colour to the 19th annual awards ceremony in fuchsia pink and aqua green.

Amy - who won the title of Best Actress at the event - oozed confidence as she posed up a storm in her Rouland Mouret floor-sweeper, which she accessorised with a black belt tied around her waist.

The off-the-shoulder gown showed off her slender figure while complimenting her alabaster complexion a treat.

And proving that simplicity is often the key when it comes to dressing for the red carpet, opted for some simple Neil Lane jewellery and a classic pair of Christian Louboutin shoes.

Meanwhile last year's Golden Globe winner Jessica Chastain looked effortlessly chic in a Nina Ricci frock, which featured a stunning trail and neckline full of ruffles.

Keeping her hair in a chic updo and simply adding a splash of red lipstick, the Zero Dark Thirty actress certainly let her dress do all the talking, opting to go without jewellery.
