Thai Customs, Respect & What to Wear
Thailand is warm, welcoming, and very used to visitors. A few cultural norms will help everyone feel more comfortable and respectful, especially at temples, around the monarchy, and out in public.
Keep Your Cool
Thai culture values calm, polite interactions. If something goes wrong with a taxi, an order, a hotel request, or a purchase, stay relaxed and ask for help. Raising your voice, arguing publicly, or showing visible frustration comes across as rude and usually makes the situation harder to resolve.
What to Wear in Thailand
Stylish, modern, and casual
Bangkok is casual but put-together. Lightweight linen and cotton, breathable dresses, pants, longer skirts, polos, button-downs, and neat casual clothes all work well.
In malls, restaurants, hotels, and nicer bars, people look polished. You do not need to be formal, but very revealing beachwear, shirtlessness, or walking around town in only swimwear feels out of place.
Cover up and dress modestly
The Grand Palace is especially strict. A scarf alone may not be accepted as a cover-up, so wear an actual sleeved top on temple days.
Everyday Signs of Respect

Respect the Monarchy
Do not joke about, criticize, meme, or casually comment on the Thai royal family. Thailand’s lèse-majesté law (Section 112) makes it a criminal offense to defame, insult, or threaten the King, Queen, heir apparent, or regent, and it is enforced. It is considered one of the strictest such laws in the world, with penalties of three to fifteen years in prison per count.
Also avoid stepping on Thai money or dropping it underfoot, since the banknotes and coins carry the monarch’s image. If a note blows away, let it roll rather than stamping on it.
Little Things that Surprise First-Timers
None of these are rules to stress about. They are the small, everyday quirks that catch most visitors off guard in a good way.

The Biggest Surprise
The single thing that catches first-timers most off guard: the anthem plays, and everyone around you simply stops. Here are the two you will hear.
National anthem, in public
The Thai national anthem is played at 8am and 6pm in many public places, including parks, BTS and MRT stations, and some markets. If you hear it and people around you stop, pause quietly and stand still until it ends.
Royal anthem, before films
In cinemas, the royal anthem usually plays before the movie, often with a short tribute on screen. When the audience stands, stand with them and avoid making a scene until it finishes.
When in doubt, stay calm, dress a little more modestly than you think you need to, keep your voice low in sacred places, and follow what the locals around you are doing.
