A t-shirt is a casual, short-sleeved garment typically made of cotton or a cotton-blend fabric. It is characterized by its simple design, round neckline, and short sleeves, making it a comfortable and versatile piece of clothing. T-shirts are popular worldwide due to their ease of wear and variety of styles. They come in different colors, sizes, and designs, often featuring printed graphics, logos, or text, making them a popular choice for personal expression and fashion. Initially designed as an undergarment in the late 19th century, t-shirts gained widespread popularity in the mid-20th century, especially with the rise of youth culture and pop icons. Today, they are worn by people of all ages and are a staple in casual wardrobes, offering comfort and style for everyday wear. T-shirts are also widely used for promotional purposes, team uniforms, and special events.
