Huge compliment.
If you're into "Bette Davis" eyes, please check out Emele Devine.
Why did you ask Lee?
Because I tried to compliment a woman on her Bette Davis eyes and my friend beside me immediately balked and basically objected saying that it wasn't a compliment to say a woman has Bette Davis eyes.
I produced the same picture as above and showed her the reference I was intending, when she was young and gorgeous and a star for being visually captivating.
My friend's reaction made the moment awkward and embarrassing for all three of us and I never want it to happen again.
She graciously said she wasn't embarrassed but what could have been a feel good reference for the rest of her life, she is young and had never heard of Bette Davis, will now forever be just a doubt about her own beauty.
Compliments involving comparisons to another woman are like trying to give art as a present. There's no guarantee the receiver will appreciate it as much as you.
