For her very first Oscar appearance, Best Supporting Actress nominee Jessica Chastain went for a Royal look by choosing Kate Middleton's wedding dress design house, Alexander McQueen, for her gorgeous red carpet gown!
Chastain, who is nominated for her work in The Help, accessorized with Harry Winston jewels, and brought along her grandma Marilyn as her date!
Unfortunately, Jessica lost out on the Oscar to her Help costar, Octavia Spencer.
