The background of the work Déjeuner à Saint-Tropez is taken from Saint-Tropez, a port city in the Côte d'Azur (French Riviera) in southern France. Before the 1950s, Saint- Tropez was only a small, little-known fishing village with a simple lifestyle. In the 1960s, after the actress Brigitte Bardot filmed Et Dieu… créa la femme (And God Created Woman) in Saint-Tropez, this quiet, unknown fishing port became a holiday haven overnight. Walking along the seashore, one can see many yachts. Big or small, tall or short, wide or narrow, motorized or sailing vessels are all squeezed together. And the work tries to bring us back to that age of purity.

The delicate portraits or brightly colored scenery in Charoy's paintings always complement each other in a poetic way. Déjeuner à Saint-Tropez depicts a young girl in the prime of her youth, wearing a long chiffon skirt and enjoying her afternoon tea in the sea breeze along the Saint-Tropez shore. Under the pearl accessories and sun hat, the girl's clear eyes make the beholder feel the coolness of the sea breeze. The scene of the port behind her and her smile is a mix of some amount of mysterious joy and freshness. The overall composition is breezy, like the beginning of summer. The artist also communicates with the viewer through this kind of coolness, leaving one with the feeling of a heart of ice held within a jade vessel.
