National Kebaya Day is observed in Indonesia every July 24 to celebrate the cultural significance of the kebaya, a traditional garment worn by women in several Southeast Asian countries. The kebaya, which is characterized by its open front and fastening with buttons or brooches, has origins believed to trace back to the Middle East and was introduced to the region by Arab merchants and Portuguese explorers. This holiday was designated by the Indonesian government to highlight kebaya as a symbol of national identity, following its recognition by President Sukarno as the national attire after it was worn by activist S. K. Trimurti during the independence proclamation. Celebrations include fashion shows and cultural events that showcase various styles of kebaya, such as Javanese, Balinese, and Sundanese, which reflect the wearer's status and regional influences. Over the years, kebaya has evolved into a fashion icon, with modern interpretations incorporating diverse fabrics and designs.
