Kate,
Thank you for your comments.
Two things I've been thinking about.
First, another actress I should've mentioned, Jeanne Crain, circa
State Fair and
Pinky. Her red hair is too dark, but she has exactly the right kind of delicate features that strike me as Jane-like.
Second, I was looking at a scene of Deborah Kerr as the Christian girl who turns the head of a handsome Roman soldier in
Quo Vadis, and she looked so good, and, yes, so jane-like, that I started to think that strawberry blonde might suit Jane better than golden-haired.
I might do some revising.
What do you think?
