@horsedraught Something I've done with avatars I've made is take the Back ponytail portion off of a Hair asset and use that, could super easily do that to come up with a similar result to what they've done. You'd have to find a ponytail base itself or edit it quickly in blender, but it wouldnt be too tough at all. Then place it where you like on the model, attach it to the head, apply physbones how you like, apply the same material and you'd be set. Could even use VRCFury to make it a toggle.
