Le Bon Marché is embarking on the third chapter of its own label Le Bon Marché Maison Rive Gauche. Following a relaunch of the private label womenswear in January, Le Bon Marché Rive Gauche has enlisted illustrator and watercolorist Tatiana de Nicolay, bringing her dreamy, nature-driven aesthetic on board for its latest collaboration. The collection brings two of de Nicolay’s hand-drawn signature prints to life. First, a reinterpretation of a navy and ecru Toile de Jouy, and a floral-stripe hybrid called ‘Bouquet Végétal.’ The prints are applied across apparel and accessories. The Belgian artist’s colorful aesthetic is inspired by her globe-trotting life. Her Toile de Jouy reflects this layered approach. Instead of the historical print of pastoral French scenes, hers features pagoda-like silhouettes, lush vegetation and delicate birds in a landscape. The capsule translates these motifs into structured jacket-and-trouser sets, lightweight organza shirts, wide-leg trousers, dresses with fluid movement and pieces in moiré, broderie anglaise and airy summer fabrics. Accessories include silk scarves and straw hats.

For Le Bon Marché, the choice to collaborate with an artist rather than a fashion designer is strategic. The store’s private label has been expanding since its relaunch earlier this year, and collaborations have become a cornerstone of the growth strategy. The retailer views collaborations as a way to reinforce its role as curator. In a saturated luxury market, department stores increasingly rely on differentiated in-house lines to build customer loyalty, capture higher margins and create unique storytelling. The store will dedicate a prominent space to the collection, including a wall installation featuring de Nicolay’s prints to build an immersive shop. The Le Bon Marché collaboration for spring 2026 will arrive in store in February.
