According to a report by Thailand Business News, members of the public—including foreign visitors—are encouraged to dress in darker clothing for 90 days. Meanwhile, all government officials, state enterprise employees, and civil servants are required to wear mourning attire for one year.

Aida Oujeh, President of the Association of Halal Trade and Tourism Thailand–Southeast Asia, said the gesture would be deeply appreciated by the Thai people during the national mourning period.

“Malaysians who come to Thailand for tourism are advised, if possible, to wear black, white, or darker tones as a mark of respect. It would be considered thoughtful and respectful by the Thai people."

"However, if visitors are unable to do so, it's perfectly fine, we understand,” she said, as reported by NST.

Additionally, Aida reminded visitors who plan to pay their respects at the royal palace, where the Queen Mother's body lies in state, to wear formal black or white clothing with a suit jacket.

In accordance with royal protocol and government directives, the national flag will be flown at half-mast for 30 days at all government offices, state enterprises, and educational institutions.

Queen Sirikit was the wife of Thailand’s longest-reigning monarch and the mother of the current King, His Majesty King Vajiralongkorn.

Throughout her 66-year marriage to King Bhumibol Adulyadej, who reigned from 1946 to 2016, Queen Sirikit was known as a glamorous fashion icon and a beloved maternal figure to the nation.
