It's weirdly difficult to get Pony or even Flux to distill the moment a woman removes her bra. This captures it... and a few moments just before. It does so from the front, the side, and from behind in various positions including lying in bed and sitting. It's pretty good at it, but it sucks at hands. Some views it does well, like close up shots of removing the bra, the fingers are well formed and correct. At distances it tends to muck things up. It likes to make things monochrome, so you may need to put that in your negative prompt. I tested it with a few different pony models, including PonyDiffusion_startWithThisOne, AutismSDXL Confetti, and Pony Realism. It seems to work in all 3. It combined well with a character LoRA I had available. I used flux to generate many of the training images, and it took literally thousands of images to make even a small training set. Use "removing bra" and "arms behind back" for best results. Enjoy!
