Of all the well-known 1950s-70s pinups, Lillian Parker is probably the most compatible with a 2019 aesthetic. Tall (most sources say nearly 6'), slender & lithe, with an impressive set of gravity-defying breasts and trimmed or shaven body hair, and a sort of timelessly modish fashion, she hews pretty close to contemporary standards of beauty.
She does however put her own twist on the template - with an almost owl-like face centered on a beautiful aquiline nose, a demure but mischievous expression, and an easy way of engaging with the camera that is the secret weapon of most mid-century pinup models. And could be noted, physically she definitely ain't shy!
She was based out of southern California in the late 1960s through around 1974, but (unfortunately for posterity) kept biographical information close to the vest. Posed in a variety of niche skin magazines of the era - for nylon enthusiasts (which her long legs showed off to great advantage), nudists, etc. She also appeared in a number of softcore film loops including striptease & girl-girl routines. Adrienne Stoute was an occasional alias.
There's at least one feature interview on her in a nudist magazine (under the name "Suzanne" IIRC), in which she seems to live a LA bohemian lifestyle - residing in Topanga Canyon, surfing, walking around naked, playing music, deploying the slang of the era - but this is most likely canned text written by the magazine to fit their pictorial. Beyond that we haven't got much. Then again, the photos themselves do nicely...
