White cotton naval shirt with short sleeves and a ½-inch navy-blue band outlining a square neckline. Each shoulder bears a white embroidered badge reading “CANADA” above a naval trade badge featuring two crossed anchors in navy-blue thread.
This insignia indicates affiliation with the Royal Canadian Navy and likely denotes a seaman branch trade. The shirt follows the standard pattern of mid-20th-century naval working dress, designed to be worn under the blue jumper or as tropical/summer dress.
