With the start of the new semester students around the country exchange their fun and fashionable clothes for boring school uniforms.

"The uniform makes us look like a bunch of clones, especially when we are doing morning exercises in the playground, "said Qing, a Senior 2 from a high school in Shanghai. "But we are not exactly the same from the top to the bottom. The boys wear different sport shoes and girls have different decorations ( 装饰品 )in their hair. These are the areas where you can express yourself" said Qing.

Although it might be strange for boys to talk about fashion, they do care about what they wear in school, especially shoes, according to Qing.

"Nike and Adidas basketball shoes, although they are still the must for many of my friends ,are becoming out-of-date,” added. He explained, "Since Liu Xiang ran so fast in Athens, running shoes are becoming popular in this autumn."

"Still in fashion are the various baseball caps and American-style T-shirts with random English words printed on them, "said Qing. "The accuracy ( 准确性 )of the written message isn't important. Often, the words are misspelt . Sometimes they do not even make sense “ Qing said with a smile.

Besides sports shoes and T-shirts, styles and colours of school bags are another opportunity for students to express their taste in fashion. Some bags are made more eye-catching by decorating them with small hanging dolls. Other fashionable items are the colourful drink contains which are now popular among girls this semester.
