I would SO buy a casual kilt in the "brown" Ulster tartan (the Ulster Provincial posted above) or in the Ulster Weathered (also posted above). I'm not partial to the Ulster Red tartan, but the other two are of absolute interest to me, even above my clan tartans (my Scots ancestry is traced through Antrim in Ulster, so geneologically [as well as geographically!] I'm closer to Ireland than Scotland).
