About L'Etoile Sport L'Etoile Sport is an American sportswear brand that fuses fashion with function. The collection, known for its clean lines, luxurious fabrics, and classically modern designs, includes tennis, golf, and activewear. The silhouettes worn by early female tennis players and the sport's enduring glamour are constant inspirations for L'Etoile Sport. "Play all day" is the company motto, a nod to the collection's multipurpose, on-and-off-the-court appeal. The rapidly-growing company launched in summer 2012 at the Meadow Club in Southampton. Its elegance, comfort, and understated chic has resonated with tastemakers from the beginning.
