"It's a match made in heaven," says Elizabeth Stewart of Roberts' red-carpet one-piece.

She's the new face of Givenchy, so it was no surprise that Julia Roberts arrived at Sunday's award show donning a custom couture one-piece designed by the brand's creative director, Riccardo Tisci.

"Julia is part of the Givenchy family now," explained Roberts' longtime stylist, Elizabeth Stewart, who outfitted The Normal Heart star and nominee in the black corseted jumpsuit with satin details, paired with black satin shark-lock sandals. "It's perfect because this look is both classic Riccardo and classic Julia. It's a match made in heaven!"

In December, it was announced that Roberts would serve as the face of the brand's Spring 2015 campaign.
