When Queen Sirikit accompanied by the King Bhumibhol Adolyadej in state visits to Europe and the United States in 1960, H. M. noted that there was a need for a modern national costume suitable for formal wear. The queen had researched and conducted data from historical records of royal dresses, and eight official designs were developed and promoted by the queen herself and her aides. There are named Ruean Ton, Chit Lada, Amarin, Borom Bhiman, Chakkri, Dusit, Chakkrabhat and Siwalai Thai dresses accordingly. Since then, these dresses have been coming into the regular use by women for ever. The last one attire we are presented and recommended for Visitors to Thailand to praise that is Thai Payook Dress. However, men's national costume is known as 'suea bhraratcha-than (royally bestowed shirt).
