Neolithic clothing was rather complex and diverse. Clothing
ranged from simple leather garments to extremely complex woven
cloth. Whole panels of cloth were woven using weighted looms
allowing for the creation of more sophisticated clothing, such as
shawls, skirts, and perhaps even rudimentary dresses. The amount of
time required to make even a single square meter of cloth could be
quite extreme, as was the amount of time needed to grow the plants
which made the fibers used in the cloth. As a result, good quality
clothing would be worth a significant value in trade.
It has been suggested that the clothing will be added as development continues and will change during game play due to new player discoveries/advancement. It is important to capture all of the common forms of Neolithic clothing, not just the basic leather tunic.
Some common items:
Wrap (leather, felt, bast[flax,cotton])
Headdress (feathers, beads, etc)
Also, the clothing will change heavily due to the time of year. Whereas a simple leather wrap and sandals might be fine for anyone in the summer, boots, fur leggings, breech-cloth, long leather shirt, fur coat, fur mittens and fur hat might be worn in the cold of winter.
It is also likely these items would be colored with paints, decorated with shells and beads, and generally not that bland (people like to decorate things).
