Since I posted the above picture I just have to add two remarks, lest anyone were to think I was endorsing the look. If I were to wear this, I would make two changes:

1) the bow tie. I would wear a self-tie black bow tie. If I were to wear a matching tartan tie, it would be self-tie if at all possible. If for some reason I had to wear a pre-tied tartan tie, I would make sure it had a matching tartan band if I planned on wearing a wing collar shirt. If for some reason I had to wear the bow tie shown in the picture I would wear a shirt with a fold-down collar to hide the band.

2) the kilt hose. It's not that I think the plain ecru hose look bad. But I think another choice would look better. I would also avoid black. I'm thinking either a mid-grey if going with a solid color; or ideally black and white diced hose.
