Hey Nick welcome to the FISD! I can speak with the little experience here, I also ordered a full commission from them. I received my arm or just a few weeks ago, but the torso and thighs were too large for me. I contacted them and they are rebuilding them. The shins and arms were perfect with my measurements. I think something went wrong with the torso and thighs, but the owner Rob is rebuilding them now for me and will be sending them out shortly. The quality was really good in the sizing match perfectly on the pieces that I did receive. There are some tweaks here and there that you will need probably such as the length of the elastic. Most of them are small things here and there. As with anything, nothing is ever perfect. Hope that helps and don't be too nervous. Anything that goes wrong with it they do correct. I sent them my measurements in inches and in centimeters just in case.
