The 501 is not a product — it's a patent that became a uniform. Since 1873, Levi Strauss & Co.'s copper-riveted indigo work pants have dressed gold miners, cowboys, rebels, and rock stars without changing their fundamental cut.
This design system channels that permanence: deep-rinse indigo as the dominant surface, red pocket-tab accents for action, cream hangtag paper for content, and Trade Gothic's condensed ALL-CAPS authority stamped across every label. Heritage utility, not fashion.
501不是一件商品——它是一项1873年的专利，后来成为了美国的制服。从旧金山淘金热到好莱坞银幕叛逆，李维斯的铜铆钉靛蓝工装裤从未改变其基本剪裁。
这套设计系统传达的是那种恒久感：深色靛蓝牛仔布作为主色调，红色口袋标签用于强调操作，奶油色吊牌纸承载内容，Trade Gothic粗体窄体的全大写字母刻印在每一个标签上。是工匠传承，不是时尚潮流。
