Gucci channels a borrowed-from-the-boys look with this oversized rework of the classic button-down shirt. It's been crafted in Italy from breathable cotton and comes in a refreshing sky blue and white color palette. Glossy buttons punctuate the piece, while the stepped hemline and roomy silhouette bring a sense of nonchalance. Drape yours over a pair of culottes for an effortlessly chic ensemble.
