The Oscar winner, who took home the prize for Best Actress in 2006, graced the red carpet at the 2021 ceremony on Sunday evening in a deep red Christian Dior halter-neck gown. The dress featured an ombré of reds, maroon, and burgundy pleats and was finished off with a black belt with a square gold buckle. She shared behind-the-scenes looks of her Oscar prep on her Instagram Stories, including close-up shots of her Bulgari jewelry and clutch options. While not every shimmering bauble made it onto the red carpet, she and her team did choose a set of dangling earrings, a pair of huge rings, and a geometric bracelet that echoed the shape of the CD buckle on her belt. Witherspoon's Instagram post also featured a cameo from her Big Little Lies co-star, Laura Dern.
