Theravada Buddhism is the religion of over 95% of Thais. However, there are a small number of Muslims (4%) mainly in the south of the country. Christians make up another 1% with a smattering of other religions.
Neat and respectful dress should be worn in all religious shrines. It is not considered polite to visit religious monuments in shorts, miniskirts or hot pants. Trousers and jeans are considered unsuitable attire for women visiting a temple.
Though shoes can be worn in temple compounds, they should be removed before entering the chapel of the principal Buddha image. Indeed, all Buddha images are regarded as sacred, regardless of size, age or position, and should all be shown due respect. Buddhist monks are not allowed to touch or be touched by a woman, or accept anything from a woman's hand.
In a Muslim mosque, men should cover their heads, even with an open handkerchief, and women should be well covered with slacks or a long skirt, a long sleeved blouse buttoned to the neck, and a scarf over the head. Everyone should remove her/his shoes before entering the mosque. Mosques should not be visited during a religious gathering.
