Along the lines of a historical outfit (not costume, right), my daughter's parochial school is having a "Saints Party" where all the kids dress up like saints throughout history. I love to get in the spirit, and I since I wear one of my kilts to church each week..

are there any canonized saints known to have worn kilts?

Of course St Andrew never went to Scotland and I've never seen St Patrick depicted in a kilt. If anyone knows, you on this board will know.
