I have just made a pair of mompei pants.
Thank heavens I intended to wear then while working in the garden - they are Japanese 'field' wear after all! I followed the instructions to the letter as to how to get the right roomy fit and, TMWOT, they would fit the back end of a bus.
Ah well, at least the length is great and I can bend and stretch and carry a fat pig or a load of weeds inside the pants if I must. Perhaps as they get old and are washed more they will 'drape' better.
