A T-shirt (T shirt or tee) is a style of shirt. A T-shirt is buttonless and collarless, with short sleeves and frequently a round neck line.
T-shirts are typically made of cotton fibers (sometimes others), knitted together in a jersey stitch that gives a T-shirt its distinctive soft texture. T-shirts can be decorated with text and/or pictures, and are sometimes used to advertise (see human billboard).
T-shirt fashions include many styles for both men and women, and for all age groups, including baby, youth, teen, adult and elderly sizes.
