Jacquemus crafts the Rond Carré long-sleeve in paper-effect jersey with a straight, minimalist silhouette. Square armholes and a ribbed crew neck define the relaxed frame, while long sleeves take cues from sleepwear proportions. Embroidered eyelets sit under the armholes, complemented by circular side embroidery and a back logo label. Style it as a layering piece or standalone statement for understated contemporary ease.
