If you only eat one bagel today, this is the bagel.
Summary
GNL (Garment Notation Language) is a formal descriptive language for clothing construction, similar to Labanotation for dance or staff notation for music. It provides a rigorous, generative system where valid expressions can unambiguously construct garments. The article introduces core concepts and includes a quick example showing how to define a t-shirt with fabric specifications and pattern pieces. The language aims to bring standardization and precision to garment design and construction.
