Formal Thai national costume

The formal Thai national costume, known in Thai as ชุดไทยพระราชนิยม (RTGS: chut thai phra ratcha niyom, literally 'Thai dress of royal endorsement'), includes several sets of clothing, or chut thai, designed for use as national costume on formal occasions. Although described and intended for use as national costume, they are of relatively modern origins, having been conceived in the second half of the twentieth century.
