What is a chef's three-piece suit?

Refers to the three-piece suit that chefs wear to work, including coat, trousers and apron. Jackets are usually short-sleeved or long-sleeved white coats, sometimes with the design of chef's hat. Pants are usually loose black or white pants, which are convenient for chefs to move freely at work. An apron is used to protect the chef's clothes from the pollution of oil smoke and food splash, usually white or black, and sometimes there are designs or signs exclusive to the chef. The design of the chef's three-piece suit aims to provide a comfortable, safe and hygienic working environment, and it is also a symbol of the chef's profession.
