When Coco Chanel came here, got a suntan, and returned to Paris bronzed, she startled the milk-white ladies of society. Today the golden bodies that line the sandy beaches of this chic resort continue the trend started by the late fashion designer. Cannes is at its most frenzied during the International Film Festival at the Palais des Festivals on promenade de la Croisette. On the seafront boulevards, flashbulbs pop as the stars and wannabes emerge and pose and pose and pose. With international regattas, galas, concours d'élégance, and even a Mimosa Festival in February, something's always happening at Cannes.
