　　United States: Casual Fridays In traditional large U.S. companies, dress codes and office‑space policies are generally quite strict. Typically, employees are expected to wear business attire from Monday through Thursday, with casual Fridays allowing jeans, T-shirts, or other informal outfits. Employees must also assess the situation—formal meetings or client visits usually call for business attire. Some companies in emerging industries like IT tend to be less stringent; reports even suggest that in such workplaces, some people show up in flip‑flops. Japan: Strict Dress Codes In Japan, both government agencies and corporations enforce fairly rigid dress standards; even during the sweltering summer months, casual clothing is off‑limits. In certain prefectures, female civil servants are required to wear a uniform consisting of a gray vest paired with a skirt, complemented by a plain‑colored blouse. With the exception of fashion and internet firms, the North American “casual Friday” tradition has never truly caught on in Japanese companies. Recently, the Japanese government launched an energy‑saving initiative called “Cool Biz,” urging public servants this summer to leave their suits and ties at home and don more casual attire. Even so, the Ministry of the Environment’s dress‑code guidelines still include certain stipulations, such as coordinating belt and shoe colors appropriately. Some media outlets have noted that past experience suggests that “dress‑down” campaigns are often difficult to implement successfully in Japan. For instance, following the second oil crisis in 1979, then‑Prime Minister Masayoshi Ohira attempted to project a new image of energy conservation by wearing a short‑sleeved suit with a tie—but his effort failed to resonate with the Japanese public. The Netherlands: Men Must Not Wear Short Sleeves Dutch companies tend to be rather conservative, requiring male employees to wear suits and ties. Once inside the office, men may remove their jackets, but they must keep their shirts buttoned—European bosses typically frown upon seeing male staff in short‑sleeved shirts. As for women, they are expected to wear tailored ensembles, usually a blouse paired with a pencil skirt. Even in hot weather, long stockings remain mandatory; while short‑sleeved tops are acceptable, sleeveless garments are strictly prohibited.
