A Summer in St. Tropez (1983)

Original title: Un été à Saint-Tropez

In an isolated country house close to the shore near Saint-Tropez, seven young women share a bedroom. Over two days, they wake, shower, breakfast, play dress up, bathe in the sea, picnic, ride bikes, pick flowers, have a pillow fight, run on the strand, practice ballet stretches, groom themselves and each other, and laugh. Anne returns a horse to Renaud; the next day, he's in a rowboat and meets her by the pier. By the film's end, all are celebrating with the lovers.
