If you are doing stills, set pose 1 and run simulation and the last frame export the dynamic cloth as .obj save your characters pose, pose 2 your character's last frame
pose wich you saved goes back to frame 1 import the exported cloth  should fit perfect unless you changed it postion do the next pose and so one
here is and example, I want a siting pose I start the character in zero postion and run simulation to sit down, I export the cloth at the last frame.
my character from the sit down postion say  turns side ways, so I saved the pose from the last frame and it is now frame 1 of pose 2 import and repeat
Note when you import the new obj delet the old one poser still rembers the collision parts just make the new one cloth and no draping.
