!!! Use LCM Lora, or an LCM model. You will be very disappointed if you don't.

504x912 and then hires 1.4x-1.7x

Based on the instagram model. She has breasts and is a woman so nothing generated is really postable here.

This is using my LCM optimized training which is impeccable for likeness. But the cost of likeness is reduced pliability of concepts outside the Lora, so you will mostly just get her kind of images with bikinis/cleavage, which usually won't be an issue. If you want to do abstract prompts or concepts you'll need to reduce the strength to 0.4-0.5 and inpaint or Adetailer her likeness back in, or don't and use this as a styling Lora for beautiful busty black women.
