A T-shirt is a casual garment typically made of cotton or a blend of fabrics. It has a simple design with short sleeves, a round or V-shaped neckline, and no buttons, collars, or cuffs. T-shirts are versatile, lightweight, and comfortable, often worn for everyday activities, sports, or as a base layer under other clothing. They come in various styles, such as fitted, loose, or oversized, and are available in a wide range of colors and patterns. Some T-shirts may also feature graphic designs, logos, or text printed or embroidered on the fabric.
