Abstract: A digital design engine of a computer-based control system for apparel manufacturing is structured to receive an order specification from a customer computing device and an apparel specification instruction from a designer computing device. At least one order item from the order specification and at least one apparel specification instruction are linked, by the digital design engine, to an extended apparel specification (e.g., a master pattern definition) such that at least one parameter in the extended apparel specification is set based on the order item and/or based on the apparel specification. The digital design engine is structured to add the extended apparel specification to a plurality of apparel specifications collectively defining a custom article of apparel.

Abstract: A reversible sling shirt may allow a patient to put on a shirt while keeping an injured shoulder with the arm bent at a prescribed, therapeutic angle. The reversible sling shirt may include a removable seam along a body of the shirt and at least a bottom portion of a sleeve. A plurality of magnetic fasteners may be sewn along the removable seam within individual plastic pockets, thus allowing a patient to put on the reversible sling shirt and take it off while keeping the injured arm bent at the predetermined angle. The reversible sling shirt may also be put on and taken off all while the injured arm remains in traction, suspended by a sling.
