Have a look at video clips of Irish pipe bands on YouTube. There are quite a few of them, and they certainly wear kilts.

Sadly, they now tend to wear tartan and glengarrys, whereas in the old days they mostly wore caubeens with either plain green or plain saffron kilts. You will see the latter kind of outfits in one clip that is headed something like old footage of Youghal pipe band. They seem to have become more Scottish than Irish over time. Mind you, you won't see any chequered hat bands at least, so I think they know that is a British army symbol.

I tend to think that the pipe bands are the only people that still wear the kilt in Ireland, which is a shame.
