Mayor in 'cool biz' style

Seoul Mayor Park Won-soon, wearing shorts, delivers greeting messages during the Seoul Youth Council meeting at the Seoul Metropolitan Council building in central Seoul, Sunday. The Seoul Metropolitan Government has adopted a “cool biz” campaign each summer since 2012 to encourage employees to wear less formal clothing in order to fight the heat without using much electricity for air conditioners, including wearing short sleeved shirts without ties. / Yonhap
