What is liveried? How to use in English

The word "liveried" derives from the Middle English term "laverel," which meant "fitted with a livery." The word "livery" comes from the Old French term "livrée," which meant "clothing" or "garment." In medieval times, lords and aristocrats would provide their servants and retainers with distinctive clothing, known as a "livery," which displayed the family or lord's coat of arms or symbols. The servants and retainers would wear these liveries as a sign of their allegiance and status. The term "liveried" has since become more commonly used to describe any individual, group, or entity wearing such distinct clothing, often in a professional or ceremonial context.
