The one bit of feedback I would provide, other than what you have already received, would be to raise the sporran up a bit, but it looks like you did that somewhere between the first couple of photos and the last string! With all respect to your wife, I think the banded collar shirt looks fine alone in a casual setting, but I wouldn't wear it with a waistcoat and certainly not with a jacket. It just seems to be a clash of styles for me. Good on ya for seeking input and, of course, mine is free of charge!
