(stop at the right edge and don't include the under apron width.(right and left in this example are as you would see them looking down as you wear the Kilt.)
And, if you are having a trad kilt made, this will not be a reliable measurement to give the kiltmaker. Most of us add a bit to the right hand apron edge to make sure that the fringe edge actually covers the underapron. I add a full inch. So, if you measured your kilt as described above, and got 37" at the waist, and sent me that measurement, I would add an inch to that when I made your kilt. And your kilt would be an inch too big. Moral of the story - as Steve and Wally have said, don't dink with the measuring instructions given by a kiltmaker, and _never_ assume that the measurements made for one kilt can just be sent to another kiltmaker. Take the time to measure using the method the kiltmaker asks you to use!
