I said this in the original thread, and I'll say it again. I own some flat caps, and love them. I will wear them with a kilt. I do, however, agree with one point made by the "against" crowd: tartan flat caps with tartan kilts is just weird. That just doesn't work.

I am curious though, I have a tartan cap on its way to my doorstep. I plan on trying it out with my black shadow SWK. I think that I'll wear them together and go find some of these "against" people and get my pic taken with them as proof of their subconscious endorsement of wearing flat caps with the kilt.
