A T-shirt (or tee shirt) is a shirt, generally button less, collarless, and pocket less, with a encircling neck and mostly petite sleeves, that is pulled on above the head and cover most of a person's chest. The sleeves of the T-shirt lengthen at least somewhat over the shoulder but not totally over the elbow. A shirt that is either longer or else shorter than this cease to be a T-shirt.
T-shirts are naturally made of cotton or polyester fiber, knit together in a jersey darn that gives a T-shirt its idiosyncratic soft texture. T-shirts are often festooned with text and/or pictures, sometimes used to publicize.
T-shirt fashions include style for men and women, and for all age group, together with baby, youth and adult size.
