The Chanel “25K” window concept extends the runway’s sculptural black ribbon into architectural form. Inspired by the Grand Palais set, the installation explores proportion, tension, and flow through a continuous band of braided satin and velvet. The material language combines sculptural form, soft-touch coatings, and concealed structural steel to achieve seamless curvature. Matte black finishes absorb light, while mirrored planes at either end heighten the sense of motion and depth. Each window becomes a composition of restraint and rhythm.
