An interesting thread this has been to one who did grow up opening doors for ladies, not just because they were ladies but because I like to feel like a gentleman. It still gives my wife a little thrill every time. I've grown and adapted to current tastes and manners all around the globe for over half a century and I retain that which suits my tastes and those in my circle.

Give all that has been presented here I'd simply second Berserkbishop's statement "I say a dress shirt and tie with the kilt will be enough, and a vest would look really dapper. I understand not being able to afford an argyle at a moments notice". You make do with what you have or can obtain without too much pain. Respect for one's host should dictate what is appropriate.
Just 2 cents more from the kilted rabble.
