Young Blonde Girl Wearing Pink T-shirt

A T-shirt (T shirt or tee) is a thin, knitted shirt which is pulled on over the head to cover most of a person's torso. A T-shirt is usually buttonless and collarless, with a round neck and short sleeves. In a 2008 USA Today survey, results revealed approximately 81% of the U.S. population have worn or will wear a T-shirt by the time of the next presidential election; 9,000 men and women were polled.
T-shirt fashions include styles for men and women, and for all age groups, including baby, youth, and adult sizes. 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 (human billboard).
