A couple of important things first. Placing the scripts into the Yabusaka Petite 3 Bento is simple. If you are putting these scripts into the original Yabusaka Petite you will need basic modding skills. I have included detailed instructions on how to do this for both petites.
So I put together this folder of scripts to enable you to wear system layers on your MODIFY petite. Its a pretty simple process. Please note, these scripts will not work if you own a no modify petite! I have already done all the work and labeled all the scripts, all you need to do is drop one script into each body part and your done. The photo is of my Yabusaka Petite 3 Female using nothing but system layers. Not all your system clothes, tattoos, skins or makeup will look perfect. You will need to experiment. So far most of the skins, tattoos and makeup I have tried work well. You may need to use a hand and feet BOM fix. I have picked up free ones or dollarbies on the MP.
