Uniforms of the Royal Marines musicians, plus cadets and instructors of the affiliated cadet organisations. This is the same as 1B dress but is worn with medal ribbons instead of medals and decorations. This consists of a scarlet mess jacket with a royal blue shawl collar, worn with royal blue trousers with a scarlet stripe, Marcella shirt and royal blue mess waistcoat. Officers above the rank of brigadier have their rank on shoulder straps, whilst all other officers have their rank marking positioned horizontally on the lapels of the collar. Officers of the rank of lieutenant-colonel wear stiff-fronted shirts and overalls (tight fitting cavalry trousers),
Trousers hose directly to their pourpoints (the padded under jacket worn with armoured breastplates that would later evolve into the doublet) rather than to their drawers. In the 15th century, rising hemlines led to ever briefer drawers until they were dispensed with altogether by the most fashionable elites who joined their skin-tight hose back into trousers. These trousers, which we would today call tights but which were still called hose or sometimes joined hose at the time, emerged late in the 15th century and were conspicuous by their open crotch which was covered by an independently fastening front panel, the codpiece.
