I got a pair (of kid ones) as a gift and wear them with white tie. Depending on one's perspective, mine are either gently aged or dirty. I always wear the left one and hold the right one, because I prefer not to shake a gloved hand myself...

But I have never found myself in need of them whilst kilted. I do agree for some kind of hono(u)r guard, but they would look silly at most black tie events...
