Sustainability is defined as the balance of a species with the natural resources of its environment and the perseverance and conservation of these over time. In fashion, the main requirement is to leave back to the linear model of buying, using and throwing away; and change to a circular model, in which they conserve most of the elements and materials of a product. A circular fashion model covers responsibility, traceability and property of the entire life cycle of a product: from the seeds and fibers; the design and the materials; dyes and finishes; the making and remanufacturing; the workers of the factories, transportation and packaging; until possibilities of the consumer to repair, renew or resell the product.
