I love the term "handsome" when describing a woman. I think it is deeper and more meaningful then words such a beautiful, stunning and pretty. It's a great term and although it may have been more common place in the past - I say bring it back. If a guy- or girl for that matter, ever describes me as handsome it may just go down as the best compliment I'll ever receive.
Urban Dictionary definition: A woman with the kind of refined beauty and attractiveness that requires poise, dignity, and strength of mind and character
