This model is mainly focused on high low skirts. It is trained on 19 images of clothing with high low skirts of varying degrees, mostly of fashion store listings.
Usagedshilo, skirt is the bare minimum you need to see this model in action.
Due to their nature, using midi skirt and full body will yield the best results so the skirt has enough length for a noticeable asymmetry that is not clipped off at the bottom of the picture.
However, that doesn't mean you can't try and make some mini skirts. It just may take a few extra generations to get a better result.
Known Issues
Because this model is based on store listings, the poses it generates might be limited. Faces and bodies will also be skewed toward "models." I recommend using ADetailer to fix faces in the generations.
