Is appearance important to the Thais?
Like you wouldn't believe. That doesn't mean you have to look like a tailor's dummy but a teacher in Thailand should look smart. And that means a necktie, a long-sleeved shirt and a pair of trousers that actually covers your ankles. Nothing will make a Thai lose respect for you quicker than if you walk into the classroom looking like you've been mugged on the way to work. (and I've worked with a few of those teachers over the years) Remember also that it doesn't end with clothes. Stinking of cigarette smoke and body odour are both absolute no-nos.
