"She is elegant rather than belle"

This quote by Wilfred Owen is describing a lady who is not always beautiful, however rather has an air of beauty and grace about her. She is not the common "belle" of the ball, however rather stands out in her own unique method. She is not fancy or over the top, however rather has a subtle beauty that is more downplayed and fine-tuned. Her charm is not in her physical appearance, however rather in her grace and disposition. She is stylish and dignified, and her presence is felt even when she is not the center of attention. She is a lady of substance, and her beauty is something that is admired and respected.
