If you just mean ''classy'' as able to look beautiful and stylish in clothes, then Audrey Hepburn gets my vote. But, as a human being, she was promiscuous and preferred married men just for the sake of dumping them
Oh dear! that was one of my choices. Read long ago that she was skinny due to malnutrition suffered when the Netherlands were under
German control. True-don't know, sounds like it could be.
Lauren Bacall is on my list
My sister was an extremely pretty lady, fussy about clothing, which I didn't understand-classy broad.
When she was accompanied by a male, she had the ability to apply air brakes when encountering a door; she would stand there with aplomb,
as the male scurried to open the door. I saw it many times, always wondered how she did that.
She pulled that trait on me, I would silently murmur, 'Damit, you have two arms;' as I too scurried to open the door.
