For the first time I disagree with Matt on anything kilt.
I bought a Miltary (British Army) kilt in a size I cannot wear just to settle in my own mind how a MBP kilt is put togeather.
It is a Reverse Knife Pleat that has the edges folded over and sewn down and is ALWAYS showing the stripe!
"Box pleat" IS A MISNOMER! 6 to 8 yards of tartan goes into this kilt.
I also have a 4 yard BOX pleat that I made, They ARE TOTALLY DIFFERENT!
My 3rd kilt is a knife pleat PV in "Pride of Scotland" Tartan and I can see the similarities.
Sorry Matt.
