Have you ever seen any students whose trousers hang so low you can see their underwear? What do you
think of that? Fashionable? Some of today's teenagers are big fans of such a look. But recently this trend has
been at the center of an argument in Italian middle schools. The headmaster of a school in central Italy has
asked students to stop wearing low-rise jeans that expose underwear and parts of the body. His request came
after a class trip,when he saw one boy's baggy trousers slide to his feet. He pointed out that this way of
dressing is not suitable for school. But in Italy, a nation that takes fashion very seriously, the suggestion caused
a debate among parents, teachers and students. The issue is whether the headmaster's request will limit students'
freedom-or whether dress in Italian schools is too casual. A parents' group praised the move in favor of good
taste, while others advised schools to stop worrying about fashion and fix up old school buildings. "We do not
want to kick fashion out," the headmaster explained, "but extremes of fashion like this are not right in school."
Many other schools have now requested that their students also stop wearing such trousers. Most students
have simply ignored the request. Ludovica Gaudio, 14, wore extremely low trousers exposing orange underwear
in class. It was cold, so she wore a matching orange scarf. Another 14-year-old said she would probably respect
the request, simply for practical reasons. "I don't really feel comfortable in those sort of jeans," said Sarah
Lattanzi, "in winter,when dressed like that, it's quite cold and I am afraid my stomach will ache."
