It would make most sense if they were various scrub outfits from Rupture Farms, and other native wear, including body paints, acquired in Monsaic Lines and other native areas. Perhaps when you beat the Scrabanian Temple you might earn Mundanchee warrior paint and feather styles. Or if you kill off enough mudokons the Cartel will reward you by renting your skin for commercial tattoos.
Also bighead mode.
