Does any one know if the Atholl Highlanders kilts are pleated to the stripe or the sett?

My father in-law, a Murray, recently passed away and as a way of honoring him I am looking at ordering a kilt in the Murray of Atholl tartan. Now I normally wouldn't consider wearing a non-family tartan but he was such a great friend to me and admired by me for his dedication and devotion to my daughter.
