I'm going to Taiwan soon and will be meeting with many important political people and a bunch of seminars and discussions with students and other people related to the upcoming election. My welcome packet says that for the seminars and such, business casual is fine. But what exactly do you consider business casual? When I worked during the summer, business casual to some people in the office meant khakis and a nicer polo shirt. I'm thinking more like slacks + dress shirt, probably no tie.
