Aprons are flexible clothing with multiple purposes. This is primarily for protection against clothing spills, stains, and debris. They also have convenient pockets to hold utensils, recipe cards, and other small items. Cooks and bakers, for example, need aprons in the kitchen to shield their clothing from food, oil, and flour splatters. Aprons are also used outside the kitchen. Gardeners wear them to protect their clothes from getting dirty and in grime. Artists and craftspeople wear them to keep paint, glue, and other messy things from dirtying their clothing. Chefs, cooks, and waitstaff must wear aprons to protect their clothes from stains, grease, and food spills. While keeping a polished appearance, the apron protects baristas and bartenders from spills and stains. In industrial settings, aprons may be designed to guard the wearer against chemicals, heat, and other potential dangers. In metalworking, welding, and foundry industries, leather or fire-resistant fabric aprons protect workers from the splashes of molten metals, sparks, and hot surfaces. Chemical-resistant PVC or neoprene aprons protect workers from corrosive chemicals, acids, and solvents.
