Fashion at the Cannes Film Festival is known for its glamorous extravagance—and Julia Fox has officially taken that reputation to new heights.

While attending the red-carpet premiere of The Idol last night, the Uncut Gems star showed out in a gauzy white gown made of iridescent (and slightly plastic-like) material. The dress was somewhat see-through, showing off a white fishnet underlay beneath the corseted bodice and voluminous skirt. it additionally included a dramatic off-the-shoulder shawl that wrapped around her arms. To accessorize, she wore sheer white opera gloves, silver hoop earrings, and a midnight blue lipstick.
