IOS tartan waistcoat

[Galician]

Tradition, man, tradition. If I remember, everything tartan other than the kilt itself is typically worn on the bias----ties, plaids, vests, jackets, those old-style tartan hose I think are called cadagh---pretty much everything cut and worn on the bias.

I see! Well, thanks, just don't feel that's something I need to follow, though, since I'm not Scottish.
