Yes, it's for G3F. Mostly because the extracted model was in a T-pose and arranging that onto a G8F rig would have been problematic.
It's also not the complete outfit, as she has stuff around her waist and a ribbon in her hair. I'm going to see if I can learn to add bones and weights for better control over such items. There are limits to what dForce can reliably do.
This outfit comes in two parts: hair and everything else.
