There's something about a loose button-down that instantly channels that effortless Hamptons boutique energy. Maybe it's the breezy silhouette, the slimming drape or the way the top is chic with white denim and worn-in cutoffs. Either way, these easy tops have a way of making everyday outfits feel a little more elevated . . . like you just stepped out of a coastal shop after a weekend getaway. Thankfully, you don't have to hop on a train to the East End to find styles that capture the look.
