A tabard is a type of short coat that was commonly worn by men during the late Middle Ages and early modern period in Europe. Generally worn outdoors, the coat was either sleeveless or had short sleeves or shoulder pieces. In its more developed form it was open at the sides, and it could be worn with or without a belt. Though most were ordinary garments, often work clothes, tabards might be emblazoned on the front and back with a coat of arms (livery), and in this form they survive as the distinctive garment of officers of arms.

An apron is a garment that is worn over other clothing to cover the front of the body. They may have several purposes, typically 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.
Aprons may be worn at work.
