Coeurl spots are used by harvesters of the tribe for best camouflage within the areas in which the flora they gather. Mostly adorn by females.
Clothing

Males use piercings more than females as part of their resilience training should they be captured by the Garleans or rival tribes. Most favored are piercings that accentuates their chest.
Due to females duty is to mostly gather and take care of the children, most do not wear piercings or accessories to avoid injury. However, when mating season occurs, females will adorn different lightweight, yet immaculate accessories of jewels, gold, and silver.
