I have a great kilt, or rather 9 yards of tartan and when I wear it, I pull the pleats by hand and belt it. I acquired a cheap brooch, that is a round circle of metal with a hardwood tapered "pin" and that's what I have been using to fasten the two tag ends of tartan over my shoulder. It's not a very high quality piece of metal and looks cheap but it works.

Any ideas on where to get a more serious piece of metalwork, better quality of the same style?

Sorry, no pictures.
