All of my contemporary kilts (3 UK's, 3 home sewed) have a kilt tile of about 5-10 degrees from low in the front to high in the back. When I wear one and I stand up from any sitting or even leaning over, I need to tug the back down and raise the belt an inch or so.
I plan to make some more kilts, HOWEVER, I hate this kilt tilt crap.
How do I correct for this in the sewing. I know in theory, just add to the back but I believe it is more complicated than that. I would like an engineer's description of how to do it correctly.
I would appreciate any valid info but please be aware that I have absolutely no sense of humor about this problem.
