Jacobite Kilt Wear Question

[Harper]

Thank you all very much. Those are very helpful.
What I was looking for was some reassurance for my own thought that it would be considered okay by the other people of the period for a gentleman's retainer to play the harp outside while not wearing a jacket.
In the Colonies during the same period a man caught outside with no waistcoat would be assumed to be a laborer or some mad person parading about in his underwear; I was wondering if the same attitude might be held toward a person in Scottish polite society in public with no jacket - just a kilt, shirt and waistcoat.
Then again, harpers get cut a little slack already and so by your endorsements I'm guessing that it's not out of reach.
Now it seems all I have to decide is whether to go full belted plaid or feileadh beag. One is more comfortable; the other is more flash on stage.
Once again, thank you all.

Cheers,
~ Darren
