I’m not saying that Marilyn Monroe wasn’t an attractive woman. She was indubitably pretty. She was certainly cute. She had a nice sparkle to her eyes and the sort of healthy curves to which men are naturally drawn.
But a great beauty, let alone a historic icon of female beauty? Not a chance. Even at her bleached, surgically-enhanced, and manufactured best, she was never more than an 8/10. And in her purely natural state, she was more like a 6.5.
Now granted, your mileage will inevitably vary. But I simply don’t see any case for her supposed status as some sort of modern Helen of Troy.
Grace Kelly or Sofia Loren that's much better
Didn't she commit suicide because she thought she was not beautiful enough? At least that's the story I heard when I was young.
