A girl who is playful and mischievous, but also wide-eyed with childlike innocence and carefree, even boyish features like short hair and looser clothing.
It's that carefree attitude combined with a natural girlish femininity--the fact that they don't appear to be trying--that makes a gamine so appealing.
It's a compliment to be called a gamine--it means your effortlessly, innocently sexy.
It's hard to pinpoint why a gamine is so sexy, it's just her attitude

Audrey Hepburn was a classic gamine
