I created a dick slip LoRA using some of my previous datasets (ahem jockstrap) that I updated with a Flux 2 9KB upgrade/upscale wash and the results were good enough I thought I'd share.

A few notes - the trigger will really help, although not entirely necessary if descriptive enough in your prompt. Depending on the complexity of the composition you want, you may need to give it several tries with different seed numbers but general it'll get it right after a generation or two.

Also, It'll work with any number of types of apparel, including towels and such, but since I used a lot from my jockstrap lora datasets, it leans in heavy to jockstraps if you don't don't have underwear type specificity in the prompt.

Enjoy.
