A t-shirt is a casual upper-body garment characterized by its simple, short-sleeved design and crew or V-neck collar. Typically made from lightweight, breathable fabrics like cotton, polyester, or a blend, it offers comfort and ease of movement. It features a straight-cut body, often with a slightly loose or fitted silhouette, and may include a small chest pocket or printed graphics. Available in various colors and patterns, t-shirts are versatile for everyday wear, workouts, or layering, suitable for all seasons.
