A T-shirt is usually buttonless, collarless, and pocketless, with a round neck and short sleeves. The sleeves of the T-shirt extend at least slightly over the shoulder but not completely over the elbow (in short-sleeve version). A shirt that is either longer or shorter than this ceases to be a T-shirt. T-shirts are typically made of cotton or polyester fibers (or a mix of the two), 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 styles for men and women, and for all age groups, including baby, youth, and adult sizes. Many youths wear T-shirts; they are great protection from the sun and useful for all wears, but the main reason being the fashion.
