I originally wanted to pleat to the stripe because it is different. And I do think that the red on green would give the kilt a very unique look.
Also very appropriate for this tartan, since the Stewart Hunting is a military tartan, and military kilts are pleated to stripe.

The Royal Scots wear the Stewart Hunting, and one of their Territorial Battalions (equivalent to the US National Guard) , the "Dandy 9th", wore the HS kilt.

The Ghurkas also use it, the Canadian Scottish Regiment (Princess Mary's Own) and the Transvaal Scottish in South Africa.

Cheers,
