The 78th Cannes Film Festival prohibits "appearance of bareness" using sheer materials like chiffon and mesh for "decency reasons" and voluminous gowns for unhindered flow of guest traffic at the festival. Assigned teams can "prohibit Red Carpet access" to rule-breakers. Tote bags, backpacks and large bags are now forbidden. Further, evening wear is mandatory for Grand Théâtre Lumière screening.
