For many years, T-shirts were simple short-sleeved (短袖的) clothes for men and boys. At first, there was only one colour—white—for all the T-shirts. 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. Middle school students, university students, and men from all walks of life (各行各业) wear T-shirts. Even women and little children wear T-shirts, too. T-shirts are worn on playground, at the beach or in town. They can also be worn for work. Yet T-shirts are not expensive. You can wear it for quite a long time. And you don"t need to spend a lot of time looking after it. Smart but comfortable and convenient to wear, they have become one of America"s newest ideas on fashion.
Although you can buy T-shirts of many materials and styles, the most popular kind is the traditional cotton T-shirts with a slogan (标语，口号) or a picture printed (印刷) on the front. A T-shirt may have one word, a popular phrase, pictures of popular singers, or an advertisement on it. As T-shirts are becoming more and more popular, new designs are coming up all the time. At first, T-shirts were only worn by women and children.
