Thailand has nominated “Chud Thai: The Knowledge, Craftsmanship and Practices of the Thai National Costume” to be inscribed on the UNESCO Representative List of the Intangible Cultural Heritage of Humanity in 2026.

Chud Thai, or Thai national costume, reflects Thailand’s national identity and rich cultural heritage through unique patterns and sewing techniques. This ceremonial clothing represents a shared dress culture for all, showcasing beauty, fine craftsmanship, and traditional knowledge. Archeological and historical evidence indicates that Thai costumes have been created and developed throughout the long period of Thai history.

In 1960, Her Majesty Queen Sirikit The Queen Mother commissioned research into Thai women’s attire from all periods of Thai history – Sukhothai, Ayutthaya, and Rattanakosin – that would be suitable for the way of life in the new era. In this way, eight styles of the Thai national costume, referred to as “Chud Thai Phra Ratchaniyom” (Royally Favored Thai Costume), came into being. They were adapted from ancient Thai dresses, and they have since become recognized as the official Thai national costume for women.

Her Majesty also bestowed three types of traditional dress for men, which have also been adapted for use on various occasions. They consist of trousers with a shirt, called “Suea Phra Ratchathan” (Royally Bestowed Shirt). The shirt styles include short-sleeved, long-sleeved, and long-sleeved shirts with a sash. Chud Phra Ratchathan is now regarded as the Thai national costume for men.

Today Chud Thai has become popular and widely known in the international community. It also serves as a bridge to promote relationships, and as a gateway for the exchange of cultural knowledge and experiences among the people at large.
