Noir Kei Ninomiya is a women's subbrand of COMME des GARÇONS, launched in 2013 under the guidance of Rei Kawakubo. Designer Kei Ninomiya, who previously worked as a pattern maker for COMME des GARÇONS for eight seasons, became the fifth designer belonging to the prestigious Japanese fashion house. As the name suggests, the brand creates designs centered on the color black, which Ninomiya describes as strong and beautiful, capable of showing different expressions through various processing techniques and materials. The brand is renowned for its sculptural, avant-garde aesthetic that blends biomorphic forms with innovative fabric techniques. Ninomiya's creations avoid traditional stitching, instead utilizing rivets, studs, interlaced straps, and even steel to achieve protruding and adventurous shapes. His designs treat clothing as organic growth around the body, creating symbiotic relationships between garment and wearer while exploring themes of shadows and light, structure and fluidity, strength and vulnerability.
