Much of the chef's uniform has developed out of necessity. The jacket, for example, is double-breasted so it can easily be reversed to hide stains that may accumulate throughout the day; the double layer of cotton is also designed to insulate our bodies against the intense heat of the stove or an accidental splattering of hot liquid. Even the knotted cloth buttons were fashioned for a reason-cloth will withstand the frequent washings and abuse buttons often take from contact with pots, pans and other heavy equipment. Though executive chefs often wear black pants, working chefs and cooks usually don pants with black-and-white checks-the dizzying pattern of hound's tooth camouflages minor spills and soilings. Today neckerchiefs are primarily worn for aesthetic purposes, to give our uniforms a more finished look, but originally cotton cloths were draped around ones neck to soak body sweat while working in the inferno-like kitchens of yesteryear.
