I think I could possibly wear a chambray shirt with every pant, skirt, short (bottom) I own. That is why I would consider it a closet staple.
And, looking at the number of posts where I am wearing one of my three chambray's, I'd say I get tons of use out of this shirt!
I was reading a post by Jessica at Here(and)Now where she stated that a chambray shirt will be added to her list of classic closet staples. And, then seeing her outfit, I knew what I was finally going to be wearing with my thrifted, and unworn, Brooks Brothers floral skirt.
