Considering the reach of traditional single-shaped sizing systems, the opportunity for multi-shape sizing systems to provide near MTM fit level is high. A novel method for human factor study, leveraging Intelligent Shaping's™ proprietary mapping algorithms, offers a means by which demographic data is sorted into shape categories. This allows brands to understand where varied body-shapes exist within their current sizing programs. Such an approach improves fit for existing customers while accommodating shape groups excluded from horizontal grading strategies. It also presents a new perspective to drive engineered fit tolerance. Body-shape sizing is an excellent change-management strategy for positioning brands for mass-customization readiness.
