In the 16th Century sailors stood out in a crowd because of their distinctive garb. Blue slops, red caps or bonnets, a white chemise with a blue doublet (not shown) became the "uniform" of all men who were associated with seafaring. Captains, pilots or ship owners had their slops and doublet made of fine blue brocades.
It was taboo to wear leather shoes on deck so everyone aboard ship were issued two pairs of rope sandals to wear during their voyage. This probably more of a safety issue than a superstition. The hold a shipwreck, discovered off the coast of Florida, was filled with rope sandals on their way to Spain.
Outer wear included woolen shawls, capes and sheep fells.
