He's fine. Dw about it.
Gear mod for most. Equipping the hat results in the headless body, equipping the top gives the decapitated head. If you want both at the same time, use 2 models. All textures by me!
Has support for the neck shapes of a few non-vanilla bodies (Bibo, Yab/Rue, TBSE-X, Chonk). If yours is not listed here try the vanilla one (should work for base TBSE), or there might be a version you can use that won't have noticeable seams - try them out.
This turns the neck connector invisible, so if this is loaded in your main collection I would recommend turning this mod off when not in use. Also, make sure you load this above Bibo/YAB as these also affect the connector.
