A T-shirt is a casual garment typically made of cotton or polyester fabric. It usually has short sleeves and a round neckline, known as a crew neck, with no collar. The term 'T-shirt' was first used in the early 1900s, and it has since become a staple in many people's wardrobes. The term 'SHORTSTOP' is a baseball position that is located between second and third base. Shortstops are responsible for fielding balls hit between those two bases and making throws to first base.
