Pretty simple test model for adding tan lines. All the tags in dataset were tweaked a little from their original ripped formats, including replacing similar tags with 'tanlines' for simplicity. I find it works best around 0.6-0.8 due to how it does impact faces, but do what you want- I'm not your mom.
Use <lora:Tanlines05:1> (or other weight) for prompts.
