>>2893515ok, so I know you said you tried this but I had success by swapping out t-shirt for shirt. and I only mentioned it once: "red shirt"..
I saw in one example you used "(red shirt), t-shirt".. maybe don't mention t-shirt at all.
I'm not using the same model as you I'm using Autism but it seems the model associates the tag t-shirt with a graphic on the front.
so, pic related is your gen parameters minus the LoRA and in Autism, only mentioning the shirt once, and "red shirt" vs. "red t-shirt"
btw, I tried a bunch of other variables too, like at first I thought maybe "oni" was associated with demonic symbols or script.. that wasn't it.
