I just finished one of these up (look in the Character Creators forum for pics of my Elf Mage Vicki WIP) and am going to get it beta tested by someone soon (my normal beta guy isn't available right now). I'll share some of the things I have found: Ignore the buttocks. Just have thigh parts attach to hips covering the area the buttocks exist in. If necessary, make a 'sit' MT to take care of bulging buttocks in sitting positions. It will generally conform properly even skipping the buttocks part and making it all thigh. If you go below the knee, you will want to add knee-bend MTs rather than adding shin parts. You'll probably also want to have Twist Left and Twist Right MTs for the hip, lThigh, and rThigh parts. This will let a user make the dress look like it's flowing naturally when the figure wearing it twists. Basically, you just twist the hem the opposite direction from the character's twist. You can then make Full Body Morphs that affect all three parts at the same time. Additionally, you can add FBMs to effect 'pull back' and 'zoom forward' effects by turning opposite morphs for each (i.e., 'zoom forward' would have lTHigh's twistLeft up and rThigh's twistRight up, making both sides flare forwards and bunch in the middle. Mine was really complicated as there were four 'danglies' that I needed to make multiple MTs for to let them swing about realistically. I could have made them posable parts with new body part names, but that seemed to border on silly. Instead I gave each an in, out, forwards, back, up, and 'jounce' MT ('jounce' is where the middle bounces up but the tip goes up but remains pointed down, as opposed to up where the whole thing curves up, tip and all -- point your wrist at the ceiling and your fingers at the floor to see the shape I mean). I've also noticed on the existing dresses (and this worked with mine) that the front hip should be thinner than the back of the hip, and flare a little at the hem. Somehow the shape seems to help keep things conforming properly, probably because it keeps things from stretching from too close to the middle when one leg is foreward.
