Shirts versus skins

Way of making sports team members visually distinct

In sports, shirts vs skins is a common form of denoting team affiliations in a pick-up game or in school; typically, when played by boys on a public court or field, such as in a city park or schoolyard, or during physical education class or intramural sports at school. The practice involves the members of one team wearing shirts while the ones of the other team go shirtless. This is used in the absence of uniforms.
