I do not use resorepless.(I am sorry, my English is not good. )
I see your character has a slim body . I mean there is a small shoulder .
I use Resorepless tool . it's can change the size values of breast, butt, thighs, legs, front hips and pelvis, lower back and belly.
but it's can't change the size values of shoulder .
I want to make a petite Tamer.
What tools do you use to adjust your shoulders?
So, I am rewriting the necessary files.
