you take your favourite blue parka and think what if I could research it into blueprint(clothing tag) that can be one time use/multi time use/one use and leared forever or traded for something.
and if you keeped the scheme you can make different versions of it with something more durable like thick fabric, kevlar, hardened skin, human/zombie skin… etc.
example: Evil islands https://www.youtube.com/watch?v=baBaypNJKok
and so you could make leather military top, thick fabric parka, kevlar cap, zombie skin hoodie, wooden boots…
also why not make clothing be able to accept attachments simular to guns
leather,cloth… padding for additonal overall defence and bite,slash,blunt… damage resistance
kevlar,metal… platings for additonal overall defence and bullet,explosives… resistance
pouches to make more storage
zombie skin attachment for masking your presence better
spikes attachment to deal damage to melee opponent
