An apron is something you wear over your clothes to protect them from the mess you make while you're cooking. Some aprons tie around your waist, while others cover your entire torso. Bakers, chefs, and butchers often wear aprons to keep their clothing clean.
A functional apron should act as a protective barrier against heat, stains, flames and more, keeping the clothes of the wearer clean and providing peace of mind that they are adequately protected from an array of risks.
