For many years, T-shirts were simple short-sleeved undershirts for men and boys. T-shirts used to be of one color -- white. And since they were worn under shirts, they were generally not seen.
    Today the T-shirt has become fashionable. It can be seen everywhere and on everyone. Women and little children wear T-shirts as do teenagers, university students, and men from all walks of life. T-shirts are worn on playground, at the beach of in town. They can also be worn for work. Yet T-shirts remain relatively inexpensive and long wearing, as well as easy to care for. Smart but comfortable and convenient to wear, they have become one of America’ s newest ideas on fashion.
    Although T-shirts are now available in a wide variety of bright materials and styles, the most popular kind is the traditional cotton T- shirts with a slogan or picture printed on the front. A T-shirt may bear a single word, a popular phrase, pictures of popular singers, or an advertisement. As T-shirts are becoming more and more popular, new designs are coming up all the time.
