I guess I missed this the first time. That's your answer then. Just substitute kilt where it says slacks and you're good to go. Of course, wear the appropriate accessories: hose, flashes, nice sporran (not a formal one), etc.

We go formal several times a year for Burns Night, St Andrew's Dinner, whisky tastings, etc., and formal weddings are quite common. If the invitation states "black tie" or "formal wear requested", a gentleman is expected to comply to the best of his ability. If you'd prefer to be interpreted as being something else entirely, by all means do as you please.
(A pet peeve of mine; people who show up to visitations, funerals, weddings, receptions, and other social events in all manner of shorts, T-shirts, jeans, etc. Second only to those who can't bear to turn their damn cell phones off for 30 minutes. It's not only inconsiderate, it's disrespectful to the point of being overtly insulting. Small wonder Western civilization's circling the bloody drain.)
That situation is becoming very uncommon in the States; this country has become VERY casual. I quite agree with your pet peeve. So many people now seem to think that "dressing up" means to put on your clean sweats.
