This Bottega Veneta tunic is cut from chunky ribbed cotton in chocolate brown with a distinctive modular construction: the turtleneck collar and long sleeves detach cleanly, revealing a partly open mock neckline and a bare back. Two exposed metal button studs cinch the waist, while an elastic band anchors the piece at the hip. The mid-length silhouette works layered over tailored trousers or worn loose as a relaxed weekend piece.
