top band of kilt

[jthk]

When people are making kilts, I notice that some folks try to match the tartan of the kilt with the tartan stripes on the top band. Some kiltmakers don't bother to match the lines and then some kilts have a different colour band along the top: some green, some black. I'm assuming this is ultimately personal preference but I suspect there may be a civilian vs. military thing going on. Could someone sort me out?

Thanks,
