I would love to hear our Euro advisers views on this. To me, my guess is that it was some other issue that was the problem. Perhaps someone else was just a better fit for the job? In most cases, you can overdress by one notch up and have no ill effects, only positives. Perhaps a turtleneck and a sport coat would have been better than the full suit and tie, but I still don't think you'd lose an opportunity over that . . .
“Humility is not my forte, and whenever I dwell for any length of time on my shortcomings, they gradually begin to seem mild, harmless, rather engaging little things; not at all like the glaring defects in other people’s characters.” - Margaret Halsey
