In&Out is a project that comes from the idea of underlining the strong relationship between lining and tailoring, and through this, the one between industrial production and manufacturing. In the field of fashion, the design of a detail can led to a consistent and recognisable visual identity system, that leads the project. Through the collaboration between the Fashion Advanced Design Studio of Politecnico di Milano and the lining leading players, seven capsule collections with different graphic patterns of tailored men's jackets are born, experimenting a new vision of the traditional lining.
