Yes, it does NSFW too :) See the section below.

Designed to achieve a very particular style of swimsuit: one with a collar, a zipper between the collar and just above the navel, and a solid back with high arm holes.

The LoRA was trained on about 130 manually cropped and tagged images, about 20 of which I generated myself to add a greater variety of viewing angles and swimsuit colors to the dataset.

Usage

Best used at 512x768 resolution. Trigger words aren't necessarily needed, but adding "innerboob" and "cleavage" to the prompt can help (unless you're trying to get a rear view of the swimsuit).

LoRA strengths up to 1 work perfectly fine, but you may want to turn the strength down as low as .6 or so if you're combining this LoRA with certain other LoRAs or want to make certain variations on the swimsuit, like adding long sleeves or making it less shiny.

Adding "zipper pull tab" can help create a more defined zipper pull tab, but it may make the swimsuit have a full-length zipper rather than a zipper that ends above the navel.

Different swimsuit colors

If you want to make a swimsuit that is a color other than black, using for example

"blue one-piece swimsuit, blue outfit, blue swimsuit"

in the prompt can be helpful to fight the model's tendency to make black swimsuits. You many also want to put

"black one-piece swimsuit, black outfit"

in the negative prompt. The model can produce most colors, but tends to make things somewhat shiny. You can add

"shiny clothes, shiny swimsuit, shiny"

to the negative prompt, or turn down the LoRA strength, to reduce this effect some.

NSFW

Try the following:

-areola slip

-covered nipples

-breasts out, nipples

Limitations

The model was primarily trained on "cowboy shot" anime images at 512x768 resolution, so it sometimes struggles with full-body shots or wide shots where the character is not vertically oriented. It can generate images "from behind" or "from side" but will often fail to have super-high armholes like the swimsuit is ideally supposed to have. However, you can often fix these problems through trial and error. It can generate some photorealistic images, but you may need to use hires.fix to prevent them from being blurry.

Lastly, it tends to make the swimsuit somewhat shiny. However, some this is more pronounced on some models than others; for example, I used Foolkat's "God of Envy" model to make less shiny images with this LoRA.
