What is the typical dress code at work and in public places? Is formal dress ever required?
Suits are rare. Most male office workers wear slacks and dress shirts, with short sleeves quite accepted. Jeans and/or casual shirts may be okay in some workplaces. Outside the office, people are quite casual, but at some of the more upscale establishments you may feel out of place in shorts. - Sep 2015
