A Helsinki high school, Töölön yhteiskoulun lukio, has decided to turn away students arriving dressed in "nasu" costumes this Friday. “Nasu” refers to an overalls-based student tradition, often worn during the beginning of the school year to identify new students, but also associated with excessive drinking. The school principal declined to comment on the decision to *Helsingin Sanomat* newspaper. This move has sparked discussion regarding student traditions and appropriate school attire. While the reasoning behind the ban remains officially unstated, it is widely believed to be related to preventing alcohol consumption and related issues. The ban signals a firmer stance on student behavior and dress code enforcement by the school administration. It remains to be seen how students will respond to the new policy.
