Just Remember!
White Duck trousers and Dark Blue or deep Red Jumpers for the ordinaries! They would've kept the Nasty salt worn clothing, lacking in color for out at sea. Nobody to see how poorly they were dressed then, working around all that tarred rigging. Hence the Term "Jack Tars". If the weather was mild many worked Bare Top! Longer hair Braided or Tied Back, Pony Tail style and Tucked under!
Some even went Barefoot. It wasn't easy working on a yard with a sail when your feet might slip, Therefore Barefoot! The actual seamens shoe back then was very similar to what women and girls wore in the fifties informally, A flat shoe, Soft and easy to slip on and off! Usually Black or Brown. Some grey from salt exposure!
A working Knife and Marlin spike were carried within sheaths secured around the waist with some type of Very flexible belt or line. Mode of dress was also dictated by either the Captain(If he was a stickler to rules,) or the Bos'n(Boatswains Mate). The Bos'n was the penultimate Deck Boss, then the Middies( MidShipmen) answered to Him and the Officers!
One of the things to build skill among the crew was a contest to the "TOP generally as fast as you could, Do not use the "Lubber" holes in the Mast platforms and go as high to the Top as you could(Don't look down). To those who are following this, Lubber holes are the access holes for rigging and crew close to the mast. As the bracing for the next level up, goes to the edge then back under the platform to the mast. The idea was to go this way and not up through the Holes I have already mentioned.
