An apron is a garment worn over other clothing to cover the front of the body to protect from liquids. They have several purposes, most commonly as a functional accessory that protects clothes and skin from stains and marks. However, other types of aprons may be worn as a decoration, for hygienic reasons, as part of a uniform, or as protection from certain dangers such as acid, allergens or excessive heat. It can also be used at work stations to hold extra tools and pieces or protect from dust and unwanted materials.

As a top layer that covers the front body, the apron is also worn as a uniform, adornment, ceremonial garb (e.g. Masonic apron) or fashion statement.
