First, note that I did not swap this model. The original swap was done here: [Only registered and activated users can see links. ] by [Only registered and activated users can see links. ]
What I did was reskin one of the models used, with the Shaman S3 leggings skin, giving the skirt model the S3 skin. Skirt model is not perfect, but very close.
Only works on female models.
Some boot/shoe models may flatten the skirt into mere shorts.
