Business casual is far too dressed up! Son in Seattle doesn’t even go for polo shirts- clean but more basic T shirts are his norm. Those who work behind the scenes, ie not interacting in person with customers, have no need to worry about what to wear. I feel sorry for those in business with their focus on appearances. Love post #12 response- seems accurate. btw- son was a software developer until he changed companies and became a software engineer. Titles depend on the company- and the job is NOT programmer, there is so much more involved!
