Hey. I generally use Dam bodies.
The dam body that has been used(Intermittently) in the last eight years is actually nearly a clone of the HT slender body but with an attached neck(The first version was released with Daryl and Rick heads, and that has no attached neck) That neck can be removed with fine scalpel work if you are using a head with an attached neck. See attached pics.
You can also do work on the pvc torso to remove muscles you don’t need to make clothing tailored for a slender body to work.
I hope these images help you out. I almost exclusively use this body. It tends to be loose in the arms and a bit thick in the thighs and(If that’s an issue), the screws for the shoulders are easily accessible to tighten them, and the thighs can be dremelled down.
If you want more pics, let me know.
