I found Flux was great at getting Marilyns hair but not her face.

This was trained on 34 high and low quality images of Marilyn Monroe in both colour and black and white, tagged with JoyCaption and manually tweaked.

It was trained at 1024x1024, 10 epochs, 15 repeats.

Not enough to completely remove the butt chin in the model.

Use it as you wish, no credit needed.
