For many years, T-shins were simple short-sleeved undershirts for men and boys. T-shirts used to be of one color--white. And since they were mom 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 teenagers, university students, and men from all walks of life.  T-shirts are worn on playground, at the beach or in town. They can also be worn for work. Yet T-shirts remain relatively inexpensive and long wearing, a.s well as easy to care for. [29]Smart but comfortable and convenient to wear, they have be- come one of America’s newest ideas of fashion.
    Although T-shirts are now available in a wide variety of bright materials and styles, [30]the most popular kind is the traditional cotton T-shirts with a slogan or picture printed on the front.  As T-shirts are becoming more and more popular, [31]new designs are coming up all the time.
