a good question from our best PM-compatible part maker today
..Cheng!...You are a specialist on Asian World, sometimes, I think on make pieces for this theme but I dont know where begin...
Maybe....Samurai items??....chinese helmets??.... 
...
but difficult one to answer, Malone!
the 'commonest' part would be the coolie hat (for chinese peasents, manchu soldiers, japanese ashigaru and even chinese/japanese civilians...from rickshaw pullers, to paddy field farmers to even Hong Kong colonial policemen)
if you don't render the surface, they can be imagined as, from straw to iron hats!
....but what if Geobra makes one later, are you gonna sue them?
like your adjustable Foulard here, if you do, design it to be adjustable, so when we angle the front brim up or down, it will give a different character to each wearer, a ninja disguised as a monk will keep his front brim below eye-level, a resting western railroad worker might wear it lazily with the brim pointing upwards to catch the wind for his face and so on...I know this will be only too easy for you
