Thailand Dress Code Guide: What to Wear and Where

Thailand's dress norms span a wide range depending on setting, and getting them right shows respect for local culture. Temple visits require the most formal approach: shoulders must be covered (no sleeveless tops, tank tops, or spaghetti straps), and knees must be covered (no shorts above the knee, no short skirts). Both men and women must remove shoes before entering temple buildings. Most major temples (Grand Palace, Doi Suthep, Wat Phra Kaew) sell or lend sarongs at the entrance if you arrive underprepared — but having appropriate clothing avoids the hassle. Government buildings and official offices also require shoulders covered and smart clothing. At the opposite extreme, beach towns like Patong, Samui, and Koh Tao have a very relaxed standard — swimwear in restaurants and shops along the beachfront is generally accepted, though it is still polite to add a cover-up when entering indoor venues. Bangkok's upscale rooftop bars and fine dining restaurants have a 'smart casual' standard — no flip-flops, no singlets. For Songkran festival, prepare to get soaked — light, quick-drying clothing that you do not mind getting wet is the right call. The general principle: when in doubt, err toward covering up, especially outside major tourist centres. Thai people dress conservatively in everyday life and are generally appreciative of visitors who make the same effort.
