Bill Pierce Not many people respect this.. I was there yesterday and there were many people in shorts and tshirts. I think that as long as you look and behave politely, you'll be fine. What you describe as your attire for your visit is absolutely fine. Are you more likely to be viewed with a higher sense of respect? yes. But would they turn you away because you're wearing shorts? I've never heard or seen this happen. FYI, I wore a long sleeve shirt and long dark jeans with dressy Adidas shoes not because of the dress code but because I enjoy dressing nicely.
Officially, you need a work permit to do this kind of work. But this is Thailand, for lack of better words, who knows. Some people actually pay to teach here and there are agencies that are built on a pay to volunteer model and officials turn a blind eye. I'll take a wild guess and say that if you pay anything to do this, then you're probably fine.
