      With the start of the new term, the students around the country exchange their fun and fashionable

clothes for boring school uniforms (校服). But not all campuses are fashion deserts. Colorful sports shoes,

school bags, T-shirts and even drink containers are breathing life into campuses.

      "The uniform makes us look like a bunch of clones, especially when we are doing morning exercises

on the playground," said Qing Pei, a Senior 2 from Shanghai Qibao High School. "But the boys wear different

sports shoes and girls have different decorations 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-have

items for many of my friends, are becoming out-of-date," Qing added. He explained that "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 (随意的) English words printed on them," said Qing. Besides

sports shoes and T-shirts, styles and colors of school bags are another opportunity for students to express

their taste in fashion. Some bags are made more eye-catching by decorating (装饰) them with small hanging

dolls. Other fashionable items are the colorful drink containers which are now popular among girls this term.

"Some teachers are surprised to see a teenager sucking a bottle like this at school and criticized it as a childish

regression (退化). But some girls just love it," said Yang Rui, a Senior 3.
