sharon tate could ahve use a LOT of muscle that last day of her life and maybe an AK-47 also!
Here's a few from the 1950's and 1960's for your edification and concideration.
Betty Page - admittedly she was on the naturally athletic side to begin with, but you only have to look to someone like Suzan Kaminga to know what might have been possible.
Gene Tierney - if you ever saw her hard-nosed Amazonian persona as Baketamon (daughter of the pharaoh) in The Egyptian - well, you get the idea.
Sharon Tate (Valley of the Dolls) - simply mesmerizing.
