All the recent, pre-St. Pat's threads have got me thinking about Irish kilts...

The original suggestion of the early Irish nationalists and Gaelic revivalists was for a solid colour kilt, as this would distinguish it from the Scottish tartan kilt that it was based on. The most likely choices are saffron to represent the ancient leine, St. Pat's blue, or shamrock green. Nowadays there are many Irish tartans available, most of which are fairly recent creations (e.g. Irish county tartans, variations on Irish national tartans) but some of which are also rather old (like the Ulster tartan). Some Irish families have their own tartans, while others may be considered (rightly or wrongly) as septs of Scottish clans.

Here is my question: do you prefer Irish kilts to be solid or tartan? Why? Pros and cons of either option?

Saying yes to BOTH solid colour and tartan Irish kilts could also be a possible answer, but I'd still like to know people's thoughts about the two options. If they are both equally good, why?
