《宋书·列传·卷五十六》
在大乱之前，军队衣服只用铠甲而已，至于军袍军袄和军衬衫必须打仗时才发，平时把它们放在仓库中，永远不会有损害。
昔事故之前，军器正用铠而已，至于袍袄裲裆，必俟战阵，实在库藏，永无损毁。
Before the rebellion, only armors were used as military clothing, and military robes and military vests were only issued during battles. In normal times, they were kept in a warehouse and were never damaged.
