The Rue St-Guillaume capsule collection brings KARL LAGERFELD’s sophisticated touch to activewear for women, offering maximum comfort and range of motion. Styles crafted from technical fabrics can be worn during workouts, while other designs are ideal for relaxed weekends or traveling to-and-from the gym. Each piece is embellished with the iconic 21 Rue St-Guillaume graphic — inspired by the KARL LAGERFELD maison in Paris — while a color palette of black and white further reflects the brand’s signature DNA.
