I'm definitely thinking for under your vestments, gents! No going "regimental" under the vestments allowed!!

Galician...Yes! The Scottish National would be perfect!!

Ozman...great tartan suggestions!

Surly Dave...I'm excited to be quoted in your sermon!

Nighthawk...thanks for your response...you certainly count, as well!

I'm not sure if guys are into this, but lots of times I see ladies wear the color of the liturgical season in their clothes for meetings, etc. For example one might wear a purple jacket for Advent or Lent, or a red one for Pentecost, or lots of folks wear white on Easter, etc. - this could definitely extend to kilts! "The more kilts the merrier", right?
I know some guys wear "themed" ties...but only because they are not kilt wearers, I'm sure!
