Cream-coloured flannel winter naval undershirt with short sleeves and a square neckline bordered by a ½-inch navy-blue band. The shirt has a long, slightly tapered cut with rounded hems at the sides. Constructed from soft, insulating flannel designed for cold-weather wear, this garment would have been worn beneath a sailor’s blue jumper as part of a Royal Canadian Navy or Royal Navy winter uniform.
The style of the squared collar and minimal stitching reflects mid-20th-century naval standards, optimized for comfort and ease of movement during active service.
