The traje de charro is a short embroidered jacket and high-waisted trousers cut in casimir wool or gamuza suede, with a botonadura — a run of cast alpaca-and-silver-plate buttons — descending the outer seam from hip to ankle. The regulations name the register: gala grey, dark blue or black, sombrero galoneado, silver throughout.

This system takes that literally. Grey wool is the ground, silver is the primary, and the botonadura's fixed vertical pitch is the layout spine. Ornament is tailoring, not decoration: it sits on a seam or it does not appear.
