The goal here is to create a shirt that is completely unbuttoned, while not revealing too much. Sounds simpler than it was to create this LoRA.
This LoRA is based on a set of 22 photo samples and trained with the PicX real model. It works with realistic and non-realistic models.
Use a strength between 0.6 and 0.8 for best results. It should work without using any additional keywords, but you may use "cleavage" and/or "navel" in case you have any issues.
Don't forget to share your images, I'd love to see what you have created. And if you have a few minutes left, make sure to have a look at my other LoRAs. Happy prompting!
