The XL lora is made for NoobAI models. Results may vary with other Loras but feel free to experiment. I've also done a DiT version for tsubaki 1.
Images in the training set are a full body standing image of a girl on one side, and 1-3 closeups to their underwear or cleavage. None have a background so I'd advise you keep the plain white background from the triggers, though it can create a background it might just get confused what to do with it. The closeups vary in angle and pose, and some training images include shorts, others skirts, a few leggings/tracksuits. There are also 2 of swimsuits, but from my attempts then model works much better with skirts. You may have to remove the upshorts from the default trigger tags.
Anyway this model aims to imitate the image structure of an artist who's Japanese name translated to heavenly march, who made a ton of this style of image. There are also about 1/3rd of the training images from other artists.
