I can wear it casually: tucked into a pair of khaki or white shorts with a preppy belt and Sperry's, knotted at the waist with capris, or haphazardly thrown on with an easy skirt (wrinkles required, of course).
I can also dress it up: belted with a pair of khaki or black pants, knotted over a maxi dress, or like I did today - tucked into a pencil skirt with heels.
Let's not forget that easy combo of denim on denim, too.
Put on a denim shirt, and you can move mountains.
(You cannot actually move mountains.)
