Coat, Full Dress, No. 1 Dress: Lieutenant, Royal Naval Reserve
Double-breasted tail coat of dark blue cloth, featuring two rows of eight gilt buttons down the front (the lowermost on the left side is missing), a stand collar faced with white cloth and gold lace edging closed at the throat via two hook and eye fastenings and fittings to the shoulders for the placement of epaulettes. To each cuff is a vertically-arranged pointed slash flap of white cloth and gold edging, fitted with three decorative buttons corresponding to each of the three points. The slash flap is bisected by RNR style braided gold rank lace, denoting the rank of Lieutenant, being a single ring of lace surmounted by an additional ring of lace that curls into a six-pointed star.
The rear of the coat is fitted with a pair of horizontally-arranged pointed slash flaps at the waist, these being faced with dark blue cloth and gold lace edging. Three decorative buttons are fitted below each slash flap, corresponding to each of the three points, while in between the slash flaps on the waist seam are fitted two decorative buttons. Above the left slash flap is a sword hook. Two further decorative buttons are fitted to the bottom of the tail on either side of the split.
All buttons are gilt RNR Officer pattern (Queen Victoria's Crown).
No. 1 Dress was worn at state occasions at home and abroad, when receiving Royalty at ports home and abroad, and at ceremonies or events when the Senior Officer considered it desirable. It consisted of the full dress coat with epaulettes, laced trousers, cocked hat, sword, full dress belt and decorations and medals.
