Chut thai

Traditional Thai clothing is called chut thai (Thai: ชุดไทย, pronounced [t͡ɕʰút.tʰāj]) which literally means "Thai outfit". It can be worn by men, women, and children. Chut thai for women usually consists of a pha nung or a chong kraben, a blouse, and a sabai. Northern and northeastern women may wear a sinh instead of a pha nung and a chong kraben with either a blouse or a suea pat. Chut thai for men includes a chong kraben or pants, a Raj pattern shirt, with optional knee-length white socks and a sabai. Chut thai for northern Thai men is composed of a sado, a white Manchu styled jacket, and sometimes a khian hua. In formal occasions, people may choose to wear a so-called formal Thai national costume.

Historically, both Thai males and females dressed themselves with a loincloth wrap called chong kraben. Men wore their chong kraben to cover the waist to halfway down the thigh, while women covered the waist to well below the knee. Bare chests and bare feet were accepted as part of the Thai formal dress code, and is observed in murals, illustrated manuscripts, and early photographs up to the middle of the 1800s. Prior to the 20th century, the primary markers that distinguished class in Thai clothing were the use of cotton and silk cloths with printed or woven motifs, but both commoners and royals alike wore wrapped, not stitched clothing. Traditional Thai attire has changed significantly throughout the Rattanakosin period.

Prior to the 1700s, Thai men and women both kept their hair long. However, following the Burmese–Siamese War of 1759-60 and 1765–67 and repeated Burmese invasions into Ayutthaya, central Thai women began cutting their hair in a crew-cut short style, which remained the national hairstyle until the 1900s.
