Chastain's all-black ensemble was an absolute showstopper, curated by her trusted stylist, Elizabeth Stewart. She effortlessly donned a chic high-neck minidress in sleek black, perfectly complemented by a matching blazer for added sophistication.
The look was elevated with a gold-linked Gucci bracelet, a sparkling ring, and a layered necklace adorned with pink tourmaline and peridot gemstones.
She chose a pair of blackout square sunglasses and a chic black leather handbag featuring red lining and silver hardware to accentuate her outfit.
