SophieFlame retardant jacquard. A geometric design made up of concentric square frames, arranged on multiple layers, intersecting each other. Sophie is reminiscent of the works of Op Art (or Optical Art), an abstract art movement born in the United States in the 1960s that uses geometric shapes to create optical illusions. Sophies simple two colour design, with its calibrated proportions and regular rhythm, has an intrinsic dynamism that is captivating.
