Read the following paragraph.

Students attending schools with mandatory uniform policies experience less pressure than do students who

must choose their wardrobes. This is because school

uniforms allow students and their parents to save money

and time. The financial investment in uniforms at

the beginning of the school year is far more economical than

the purchase of an entire wardrobe of designer

clothes and trendy styles. Students who do not have to

deliberate what to wear each

morning are able to invest their time in more productive ways, such as studying for

tests or finishing homework. Uniforms

may stifle students' self-expression, but there are many other ways to

reveal one's individuality at school.
