A Lora to get the classic leather harness that forms a X with a ring at the center of the chest rather than the more common H style harness.

Trigger word: "X-harness".

Do not put "leather harness". That seems to generate the H style harness that is more common in most checkpoints.

Version 1 is trained with mix of images with/without cock ring strap. To get the cockring strap, add "with cockring strap". Doesn't always work.

Version 2 is trained with images with cock ring strap. You should be able to get a cock ring strap with cock ring most of the time without specifically prompting for it.
