On the Croisette, the dress code dos and don’ts often turn into don’t-cares–see how celebrities have bent the rules over the years.
Cannes Film Festival has decided to play fashion hall monitor this year, updating its red-carpet dress code with some surprisingly prim guidelines. In a pre-festival curveball, organizers banned the infamous “naked dress” entirely (those barely-there sheer gowns that were practically a Cannes trademark are now a no-go) and even outlawed the mile-long trains that used to send photographers scrambling. It’s a crackdown that basically says less skin, less drama, more decorum on the Croisette. For an event known for over-the-top glamour, this sudden modesty mandate has everyone raising an eyebrow.
But let’s be honest, no fine-print dress code can snuff out Cannes’ rebellious streak. For decades, the festival’s red carpet has doubled as a stage for style revolt, with A-listers routinely coloring outside the lines. Some swapped out ball gowns for barely-there slips or daring hot pants, while others made statements by kicking off their stilettos mid-step. And not an ounce of glamour was lost in the process — if anything, those rule-breaking moments are the ones everyone remembers.
