The Maya used dress to help them structure social interaction. Taking a behavioral chain and practice approach, I define dress elements of male courtiers and how they were combined into outfits during the daily practices of dressing and attending court. I identify two groups of headgear, Standard and Special, among courtiers on vases showing historical interaction among humans. Each vase is considered commemorative and must communicate to an audience. I identified six Standard hat types that were widespread in the Maya Lowlands. The distribution implies a basic set of recognizable roles that provided the political-religious structure of the typical Maya court, perhaps as early as the Late Preclassic period. Four of the hat types are connected to glyphic titles. Each titleholder's position in the vase's visual space implies a hierarchy of roles. The results support my hypothesis that dress does identify social roles in the Maya court.
