Someone asked before if there were naked Asian people, and the answer at the time was no. I was thinking of them in the traditional Asian loincloths.

What for? Japanese soliders stationed on tropical islands had their uniforms decay. Also, North Korean soldiers had their uniforms taken when captured by UN forces, and South Vietnamese had to remove their uniforms when the North Vietnamese won.

Valiant Miniatures has a Montagnard in a loincloth in white metal that could be used. If I remember correctly, the long portion of the Montagnard loincloth were parts you glued on, so I am sure the figure could be converted to any sort of asian nationality wearing a loincloth.
