Have not been very successful with this particular fetish so I decided to try my hands on it.
※Still very much unstable and will likely shows stockings on both legs without weighting.
※The loose stocking fabric might not look like actual stockings. Working to improve it.
※Version 1.1 is trained on CivitAI. Showcase includes some images generated locally with this model.
※Version 1.2.1 is retrained locally to improve on stocking heights accuracy. It does work better, but still might not be as high as you might want.

Trigger words

one bare leg, pantyhose, pantyhose partially removed, pantyhose around one leg, loose pantyhose,

Optional

To a certain extend, it is possible to adjust for where the pantyhose goes up to with:

• On thigh (above knee): loose pantyhose around thigh

• On calf (under knee, above ankle): loose pantyhose around calf
  However, this is currently the default result so you might not need to add this.

• On ankle: loose pantyhose around ankle

Generation notes

• You might want to weight down on pantyhose around one leg to have less chances of having stockings on both legs. During testing, I often had to weight it at 1.2.
  + Might occur without weighting (even with one bare leg):

• At times, the model would still produce results where there are partially stockings visible on the leg that should have been bare (often seen around the foot). This has been a problem since initial versions and v1.0.
  To counteract this, you might want to add one bare foot from v1.1 onward.
  + Might occur without one bare foot
  

• The optional (stocking height) is not working well, especially for loose pantyhose around thigh. In most cases, it would still default back to around calf level.
  Would still produce results where the pantyhose is around thigh if the leg is not shown clearly below knee. This could be achieved through the use of no knees visible, no knees, or adding visible knees, knees to negative prompts. For good measures, I would do all 4 of those.
  
  Another possibility is when the character is on all fours.
