The garments industry treats a uniform like a simple piece of clothing, but the serious practitioner, instructor, or retailer treats it as a system with measurable properties. Understanding how a uniform is built, why it is built that way, and what it is supposed to do will change how you buy, maintain, and evaluate your own gear.
