Formal black wool mess jacket belonging to a Royal Canadian Navy officer. The jacket features six gold metal buttons on the front (arranged in double-breasted style), gold lace rank insignia on each sleeve (four stripes with an executive curl at the top, denoting the rank of Captain), and “CANADA” shoulder titles embroidered in white.
The jacket is cropped at the waist with pointed tails at the back, fully lined in black satin, and includes an interior pocket on the left side. Light padding reinforces the shoulders.
This garment would have been worn as part of a formal evening “mess dress” uniform for senior officers in the Royal Canadian Navy, typically accompanied by a matching black waistcoat (see 2020.526) and trousers (see 2020.525).
