There's an interesting article in the NY Times today regarding new policies on summer business dress in Japan. They're calling for no jackets and ties to save on air-conditioning and pollution: http://www.nytimes.com/2005....ted=all I think it's an interesting idea, but couldn't they just wear summer suits? I find the excessive AC in NY offices in summer really annoying. You dress for the outside weather, and then freeze inside the office. It SHOULD be colder in winter and hotter in summer.
