Taking a cue from Madonna, Sharon Stone donned a beaded Valentino romper with a skirt overlay for the 1995 festival.
Only Kate Moss could wear a grey Narciso Rodriguez sheath to a black tie event. Then-boyfriend Johnny Depp adhered to dress code, though, for the 1997 festival.
Naomi Campbell, a fixture of the festival, appears at the annual amfAr gala in a sheer, paneled gown in 2001.
Tilda Swinton walked Viktor & Rolf's Fall 2003 runway show, acting as the design duo's muse. In 2002, she wore one of their Fall 2002 collection designs to that year's Cannes festival.

For the 2013 premiere of her Coen Brothers film Inside Llewyn Davis, Carey Mulligan selected a black-and-white Vionnet look, and accessorized with a little Justin Timberlake.
