I was trying to upscale this image in img2img to 1024x1024 and was really struggling. I couldn’t preserve the patterns in her gown and for some reason the gown wouldn’t stay in her right hand, it’d fall against her leg, and was longer for some reason. Trying to force-correct these things often ended up with distortions. Any ideas?

Example of fail

    What about upscaling it normally and then using img2img with a really weak strength (or whatever its called when you turn the noise option up high and it makes the image mostly the same, I don’t remember the name of it). Or maybe just try that without even upscaling it first, just play around with that noise setting, high values should make the image change less.

        Yeah, that’s the one. Keeping that pretty high will only change the image a slight bit, and should therefore keep OP’s image mostly intact (with the added benefit of being processed at a higher resolution)
