Good for him! I was once in a similar situation to you, and now rather regret having said nothing (sometimes people react to compliments in an embarrassed way, so silence is probably advisable). But the lesson from this incident is surely that the successful attempt of this gentleman is surely worth making. We all need a bit of self-confidence.Earlier this week...I saw a guy (mid-thirties?) wearing a nice tweedy-looking suit with a tie that went with it very well. Over his suit he was wearing both a classic trench coat and a fedora...he looked entirely natural in it and it didn't come across as "costumey" at all...very rare these days to see a man daring to go the whole nine-yards and totally succeeding.
