If we're going by photographs, Liz Taylor, Jacquline Smith, Marilyn Monroe, the one who played Wonder Woman, Bridget Bardo, Maureen O'Hara, My Mother, Myrna Loy.
If you ask freshmen boys who've just studied Romeo & Juliet, Olivia Hussey.

Excellent's pics all, I agree!
I agree with all of your picks! Myrna one of my favorite actresses.
I also think Ginger Rogers was stunning. She was before her time.
Olivia Hussey in Romeo and juliet. Brings back memories of HS English when the girls cried while the guys tried to keep their desks from rising.
Yep. In high school, our English class was twice loaded onto buses to go to a local theater to see Romeo and Juliet.
During the balcony scene, not one boy in the theater said a word.
