Okay, here's mine, a box pleat I made in the Forbes tartan, with a jacket I also modified. Jacket's not perfect. The lining was actually too small for it, so reattaching it would've puckered the bottom of the jacket...

Maybe one day when I'm not trying to procrastinate, I'll modify the jacket to make it fit tighter like a kilt jacket, and also adjust the lining... We'll see.

Anywho, the pictures:
