White cotton naval undershirt featuring a square neckline trimmed with a ½-inch faded navy-blue band. The shirt has short sleeves and a straight-cut body with small metal snap fasteners at each lower side seam. The garment is simple and unadorned, designed to be worn beneath a sailor’s blue jumper as part of the Royal Canadian Navy or Royal Navy working uniform.
This type of undershirt was standard issue during the mid-20th century, recognizable by its square collar opening matching the iconic naval style.
