yung-rage:

     Although their ancestors surfed comfortably in the nude, modern trolls will generally cover up when around other races. Loincloths (such as the Hawaiian malo) are worn by men and women alike and are considered the uniform for the sport. Brassieres are less common, and the torso is usually covered by trinkets, jewelry, shells, and flowers worn to elicit the favor of the loa. For this reason, costuming can reach levels of record gaudiness during formal competitions. When alone, a troll will find more comfort surfing bare with only one or two lucky trinkets on their person.
