Avonlea,
I think the kilt, sporran, hose, and shoes look fine. But I think the red shirt is a bit much. If we go back to Hamish's guide to a balanced outfit, I think a white dress shirt would be better. The balance would be that the hose and shirt match, the flashes match a minor color in the kilt, and I think the tie ought to match the flashes. The kilt should be the center of attention. I just think the red shirt would over power the kilt.
