When we're jonesing for new gear, we often don't give enough credit to our basics. One such basic may just be that classic button-up shirt hanging in our closet. Consider that a button-down can be as laid-back as it can sophisticated, or as chic as it is uncompromisingly cool — not to mention, practically seasonless — and you might look at it with fresh appreciation. We've culled 15 of our favorite celebrity examples wearing the button-down in classic cotton, silky fabrics, bright hues, and sweet printed versions. Freshly outfitted iterations from Jessica Hart, Kirsten Dunst, Emmanuelle Alt, and more of our faves make quite the case for their unmatched versatility — just click through to be newly inspired, then shop the looks for yourself.
