The X Kilt instructions....it's not a "pattern"..... can be made to work just fine for large guys. Now, REALLY overweight guys....that's tougher. By that I mean guys who's gut circumference is more than 2-3 inches bigger than their butt circumference. It can be done, but I don't get into how to do it in the instructions. However, questions about such issues, asked on the DIY forum will probably get good answers from myself and especially sydnie7, who is a better seamstress and tailor than I am...as well as several others.
