You are correct. In the Twistys set I saw similar ear rings and a black necklace and the top of the stockings but the nail polish does not match her hands in your samples.
This will be a challenge... she has been modeling for a long time and is very prolific.

She did these when she was just starting in the glamour business. They are not as explicit as the previews would suggest. The guy talks over it all and she hardly speaks. You can search other forums for his name and maybe found some...
It sometimes looks like the film producer decides her "age" based on the audience he's selling to, "feeding the fantasy".
Anyway, she does seem to keep fit at her "mature" age and her giggles are very distinctive.
