The globe-hopping jet set has descended on Cannes, and while style matters, it's really all about size—yacht size. Alberta Ferretti's 148-foot Prometej will be docking off the beach, as will the Missoni clan's 162-foot Pegasus. Meanwhile, Roberto Cavalli's 135-foot R&C makes up for its (relatively) diminutive stature with all the subtlety you'd expect from the man who gave the world leopard-print eveningwear: It's painted with an iridescent lacquer that gleams electric-purple in the sun and softens to navy at sunset. We checked—Hypercolor's not involved.
