Based on star-power and who was consistently "A-list" throughout.
Pre-60s, black-and-white actresses.
I know in any top 10, Bette Davis, Joan Crawford and Katharine Hepburn would be at the top. Who else? Vivien Leigh? Olivia de Havilland? Who else completes the top 10?
I know Hepburn was considered box office poison at one point in her career, possibly Crawford and Davis were as well.
Greer Garson, Gene Tierney, Greta Garbo, Ingrid Bergman, Hedy Lamarr (that's HEDLEY) - all gorgeous and glamorous black and white goddesses.
Marilyn Monroe, Elizabeth Taylor, Grace Kelly and Vivien Leigh all started out in black and white.
She had the good sense to go out on top, quitting when she turned 40.
R3, FYI: "Box Office Poison" was the title of an infamous article that appeared in The Independent Journal in 1938, listing ten (formerly) popular and expensive-to-hire stars who could no longer attract moviegoers to the theaters. The ten were:
Dolores del Rio
Of these, Garbo, Crawford, Dietrich, and perhaps Hepburn rightfully belong in the glamour actress pantheon. Shearer, Francis, and del Rio were certainly glamour queens back in their day, but so many later stars (Hayworth, Gardner, Taylor, Kelly, etc.) have surpassed their legacy over time.
TOP TEN (my first 8 are solid but last 2 are disputable choices):
Vivien Leigh or Ginger Rogers
Ingrid Bergman or Grace Kelly
Ingrid Bergman is one of the great cinematic beauties as well as a great actress. She tops any list of glamourous women.
No Olivia de Havilland (or Joan Fontaine) love?
Ava Gardner started in small roles in 1941. She's definitely a glamour girl, one of the most glam.
I don't know if she was always A-list, once she started getting leading and second lead roles.
The two most reliably A-list actresses of the studio era were Shirley Temple and Betty Grable. Both are unwatchable today, but in the thirties and forties both were insanely popular and queens of the box office.
They were far more popular than any of the interesting actresses on OP's list.
I have replaced both Vivien Leigh and Ginger Rogers with Marlene Dietrich.
And Ingrid Bergman, not Grace Kelly.
That's a perfect 10.
What about me?
Not to go against OPs premise, but..Which actresses are most remembered today, and which of them have the most movies that are still popular today? I don't think Marlene Dietrich is as well known today by younger people, mostly because she wasn't in any huge hits (that are still widely known today). Betty Grable may have been huge then, but you don't hear much about her now.
With that in mind, I'd say the top 10 from that era, in terms of popularity and name recognition today are:
Glamour? including Irene Dunne is applying an interesting definition (although I love her). And was Bette Davis glamorous, ever? Mae West was too comedic and stagy to be glamorous. But that's just my opinion.
To me the key elements of glamour are mystery, beauty and aloofness/an untouchable allure. So I'd say number one is Garbo.
Greta Garbo (No one approaches her in the ranking. She is it.)
Marilyn Monroe (A ringer in the group - her glamour wasn't high-tone, and her "mystery" was unlike any of the others.)
Elizabeth Taylor (If we're talking pre-1960, she just about makes the cut.)
Merle Oberon (Can't stand her, but I think she fits the profile.)
How often was Bette Davis a glamour girl? Don't ask her Mildred in of Human Bondage.
Yes,  your top 5 are definitely the goddesses. Breathtaking beauties all.
If we're talking GLAMOUR girls and it's the 1930s, the Top Ten are indisputably:
I'm not talking about who is best remembered or who is best known by children today.
These are the women who IN THEIR DECADE were considered the most glamorous by world-wide audiences.
Rare color footage of 1952 Academy Awards red carpet arrivals.
Ginger Rogers' escort was smoking hot.
Gloria Grahame appeared a bit disheveled.
Joan Fontaine wore a gown that could be worn today.
Ronnie, Nancy and Jane Wyman at the same event!
I'm watching "Her Highness and the Bellboy" right now on TCM. Hedy Lamarr was really incredibly beautiful.
If she had possessed a bit more talent...
Also: Rita Hayworth.
[quote]Ginger Rogers' escort was smoking hot.
That's her husband, Jacques Bergerac. He was also married to Dorothy Malone. He's probably best remembered as Eva Gabor's skating instructor in "Gigi" and as the hypnotist in the weird B-film "The Hypnotic Eye."
As much as I disliked her as an actress, I have to admit that Jeanne Crain looked exquisite on the 1952 Oscar arrivals clip.
All dead, except for Nancy Reagan and Zsa Zsa.
Ba-rump-a-bump-bump . . .
Glamour? What do u mean, exactly? Many of the actresses mentioned here are more known for their talent than glamour. Of course the were all attractive but do you mean the way they dressed, their onscreen persona or what?
