In Kelantan, the traditional pattern that existed in the designing the costumes for ‘Makyung’ exhibits the combination of organic and geometric styles. This balances and reinforces every produced design. The use of aesthetical values in designing patterns with underlying decorations is directly created to mirror the activities within its social community through resources that reflect their customs and culture. Based on the displayed designs, we can learn one branch in JKKN’s ‘Makyung’ performances in Kelantan. The research on the conservation of aesthetical values in designing traditional pattern for ‘Makyung’ costumes is a qualitative research, carried out descriptively through observing and analysing the performances, as well as interviewing the costume designer which entails the analysis of aesthetical and sociocultural values to explain the connection and role of the traditional designs in the costumes. The result of this study on the conservation of aesthetical values will be able to help the society to understand the development of ideas, creativity, aesthetical values, and meaning in every performance as well as the factors that support the process of designing traditional patterns for JKKN’s ‘Makyung’ costumes in Kelantan based on its sociocultural system.
