To follow up my 70s version of Kitten, here's her more mature look from the early to mid 90s.

My advice to help get a reasonable likeness out of this one is to stick with a strength of at least 1, maybe a little higher, 1.2 to 1.3, keep the denoising down to a minimum if upscaling, and deploy the prompts "heavy makeup" and "mature female" to adjust her look and age as desired.

Can do SFW, but you'll have to be insistent about it.
