 Sumptuary regulations regarding dress and ornamentation were carefully observed as a means of reinforcing social hierarchy.Designs with the peacock insignia were strictly reserved for the royal family and long-tailed hip-length "htaingmathein" jackets and surcoats were reserved for officials.Fabrics with metallic threads, sequins and embroidery were limited to royals, high-ranking officials, and tributary princes ("sawbwa").
