Crazy question - I know.... I know what I would wear to a Billy Joel concert - jeans and a polo. I know what I wear to the symphony - a suit or better. What do I (and my wife) wear to a Diana Krall concert? Business casual? A suit? Khakis and a casual shirt? For those of you who have went to one of her concerts, what was the typical dress? Thanks, Mike P.S. My wife and I are going to the concert tomorrow evening at the Midland Theater in Kansas City, MO.
