Abstract: A unique methodology for apparel mass-customization is provided. Tracers, precision garments designed for fitting at a store site, are provided. Tracers work in conjunction with a unique Clip and Alteration Point relationship. A database of customers' unique digital fit data is provided. Such data are used by a configured system to generate patterns reflecting a customer's personal size as well as level of comfort. [Virtual inventory is enabled by such stored data and are applied to electronic patterns with no shelf life.] The database allows customers to reorder additional pants in new styles and fabrics at any time. Automated patternmaking algorithms are used that dynamically adjust patterns to the data; core style patterns are adjusted to fabric specifications. A sophisticated manufacturing process provides separates and independent sub-processing, such as kitting, enabling cost-effective and rapid one-at-a-time apparel creation. An exemplary channel kiosk and channel kiosk with scanning are provided.
