According to the Thai Minister of Culture, Cambodia put on public display on the stage of its Miss Universe 2026 contest without attributing proper sources a photograph of period costumes saying it was of Cambodia while, in fact, the print was taken in Kamphaeng Phet province of Siam (Thailand) in 1906 (B.E. 2449) during the reign of King Chulalongkorn. The Royal Photographic Glass Plate Negatives and Original Prints Collection was registered at the Vajirayana Royal Library and is preserved by the National Archives of Thailand. In 2017, UNESCO formally recognized the collection in its Memory of the World International Register and advised the Thai National Archives to keep the glass plates.
Design of Thai costumes for both males and females has evolved during the past several years and decades, some of which can be seen or observed in the following pages. Designed Thai dresses have been shown to audiences in the Netherlands, France and Japan. In the latter country, traditional Thai fabrics have been adapted as kimonos for the Japanese audience.

Chok (จก) is a densely figured fabric in which the foundation warp and weft are supplemented with an additional, patterning weft. It is the textile heritage of the Thai Yuan (also known as Northern Thai) community, originally from Chiang Saen, who now resides in seven provinces – Chiang Mai, Nan, Lampang, Uttaradit, and Phrae in the North; and Ratchaburi and Saraburi in Central Thailand. Originally used as the narrow, colorful hem border on women’s traditional wrap skirts – pha sin (ผ้าซิ่น) -, chok may be woven of cotton or silk, and is sometimes augmented with metal threads. Among the Thai Yuan, the fabric functioned as an indicator of status; the more silk, gold, or silver thread it contained, the higher the owner’s social and economic position. The patterns found in chok cover a wide range of designs, from stylized flowers, birds, and animals to a variety of geometric motifs such as hooks, squares, diamonds, and zigzags.

Chok is woven face-side down on the loom. To create its intricate motifs, the weaver raises the warps with a pointed instrument, such as a porcupine quill, to create a space to insert the colored pattern wefts. The painstaking process makes weaving chok extremely time-consuming.

Revitalization and Preservation
By the 1970’s, there were few chok weavers left. However, in 1977, Her Royal Highness Princess Maha Chakri Sirindhorn chanced to meet Mrs. Son Kamlanghan (1903-1993), a native of Ratchaburi province and a master weaver of chok in the style of Khu Bua, her hometown. The craft was then on the verge of extinction due to lack of young weavers to carry on the tradition. At the suggestion of Her Royal Highness, Her Majesty Queen Sirikit the Queen Mother (then Queen Consort) invited Mrs. Son to work as a trainer at the SUPPORT workshop at Klai Kangwol Palace in Western Thailand. The SUPPORT Foundation was founded by Her Majesty to preserve and promulgate traditional crafts as well as provide needed assistance to craft-producing communities across Thailand.

Mrs. Son’s lessons created a new generation of weavers who preserved and built upon the craft of their ancestors. After Mrs. Son’s death, her daughter, Ms. Thongyu Kamlanghan took over the task of preserving the now-flourishing art of the Northern Thai style of chok weaving. Today, chok fabric is produced in many Thai Yuan communities. Famous centers of production include Mae Chaem district, Chiang Mai province; Laplae district, Uttaradit province; Ratchaburi province; and Sukhothai province, among others.
