I generally think that a woman with a great personality is true class all in itself. But many think of it in other ways also. Friendliness, cleanliness, education are all important also. You'll find that there are many meanings to a woman being classy. But to me, it's that great personality with laughter and compassion that means class to me.
The dictionary defines it as " stylish and sophisticated". I think it's a bit more. To me it's someone who despite the given situation will handle all things with dignity.
If she eats pizza and drinks her beer out of a glass rather than from the bottle, she's a classy lady in my eyes.
