I am sad myself about khrys's maps not being in the base package, but on the pluss side, it will cost less than it would if it had. I am not sure what you mean by buttocks thing to work, but, I will honestly say that this outfit will have less poke thrus than V3 ultra catsuit. I find there is one problem that I can not fix, it happens when either leg is moved forward into the exteme range(when thigh is adusted upward toward the chest). It causes a poke thru in front to the thigh and a little in the buttocks. One can always character inside invisable or if that does not apply with transparent MATs, one may have to avoid that pose. I have found with all clothing that sometimes you should transfer movement to the buttock or to the leg or vise versa. When you are covering this much of the body with one peice of material, its impossible to get absolutely perfect, but if you are familiar with my products, I will tell that this outfit fits better than anything I ever made before. For those of you who bought my MiniDress, I have found that if you transfer most of your thigh movement to the buttock, the bottom of the skirt will flow much better. thank you marty
