Re. "Sigh ... I Dunno"
There are probably better pictures of Audrey Hepburn that you could have gone with. Like this one, for instance.
But if we're talking period-film crushes from the "golden age and beyond", I'm more inclined towards either Natalie Wood ...
... or Ingrid Bergman.
Heck, in The Bells of St. Mary's, Bergman even looked pretty hot in a nun's habit. (But I'm probably going to hell for saying that.)
Well, sigh ... I dunno either. But thanks for inspiring the diversion.
