but I wanted to go all out, as if I were one of the painted hooligans attending a college sporting event

In all seriousness, I had thought about using a cap badge when not in tartan, but I hadn't really seen this done and thought this might be a huge faux pas. Also, it seems like it could be a bit much due to its size. I have not come across a lapel pin, but that might fit the bill quite nicely. To avoid the "walking billboard" syndrome while in tartan, I did a bit of searching last week and found a simple holly brooch to use for a kilt pin on my clan tartan once it comes in (hopefully before the end of the year). Holly is the plant badge of the clan associated with my name (if only the clansmen of auld had foreseen what we would do to the holly come the holidays, it would have been a much easier search). Beyond that, it seems to me that the only other place that could have a symbol displayed would be a cap badge, if one were wearing an appropriate headpiece. As for the rest, I have to agree that shoes, socks, belts, and the like have no business displaying every little symbol that strikes your fancy (simple patterns can be okay), unless the situation deems it appropriate, as in the aforementioned college sporting event.

and thank you, your insight in this issue has been very helpful. I don't always see eye-to-eye with your views, but I find many of your posts to be quite informative and enjoy reading them.
