I initially trained an "eyepatch bikini" but didn't like that it still produced an eye patch, so I adjusted the caption to include "square patch bikini" and when testing it with, and without the LoRA I got the exact same results so I dropped it as useless but when revisiting this concept I couldn't reproduce the eyepatch bikni without a LoRA so I trained a new one intending to use the term "square patch bikini", again, and this is the result.

This is eyepatch bikini, which I believe is well known in the Anime circles, and I wasn't able to find any reference to it in fashion so the source material is limited to synthetic though I don't see that as having caused any issues that I care about.
