The law firm that I'm going to be working at this summer has a 'business casual' dress code for the summer time (full business dress the rest of the year). Everyone keeps saying that 'business casual' is a lot more complicated than dressing up in a suit. My question is, can't you just wear the same dress shirts that you would wear with a suit, but without a tie and the top button undone, and a pair of regular trousers? Especially for the summer months where, it seems, a blazer is not necessary. Am I missing something? Last summer I worked for a federal judge that allowed us to "dress down" on Fridays. The dress down rule was that we didn't have to wear a tie. This same style seems appropriate to me for places with 'business casual' as well.
