As you are probably aware Thailand is an exceptionally hot country, where, if we could, we would all be walking around in singlets, shorts and flip flops. Unfortunately though if you want to create a good impression, shorts and flip flops are for children. Wearing shorts to the shops, grabbing a coffee or relaxing with friends is fine but on a night out, eating in a nice restaurant or doing anything official with the Government or school, shorts are really not acceptable. A nice dress, skirt, jeans, chinos and combats are more fitting, will set you above the normal everyday tourist or backpacker and show you are a valuable member of the local community.
Local and Employment Dress code
Thailand has a unique colour coded days of the week system which is incorporated into the Monarchy. Monday is yellow, Tuesday is pink, Wednesday is green, Thursday is orange, Friday is blue, Saturday is purple and Sunday is red. Each member of the Monarchy has their own flag based on the day they were born. The current and much loved Monarch is His Majesty (HM) King Bhumibol Adulyadej (Rama IX) who was born on a Monday and thus yellow has huge importance to the country and is seen everywhere. His beloved wife Her Majesty (HM) Queen Sirikit was born on a Friday and Hence the significance of the blue flags. Throughout the history of Thailand there have been many Monarchs, the most influential of who was His Majesty King Chulalongkorn (Rama V) who was born on a Tuesday making pink one of the most important colours in the country. The mojority of schools in the country follow this code for their staff uniforms, on Monday everyone wears a yellow shirt, on Tuesday a pink shirt etc. Although having some sort of clothing of each colour would be a bonus, it is crucial that you have a yellow, pink and blue shirt/blouse in your wardrobe.
Returning to the heat of Thailand, teaching in a school is hard work, depending on your class you might or might not have air con but to be honest, it really won't matter, you will be hot and sweaty all the time. Again, you might feel like wearing shorts, sandals or a floral light weight summer dress, unfortunately again, this isn't acceptable attire for a teacher.It's going to be hot whatever you wear, so you might as well wear clothes which will create a great impression. To do this, think about what you would wear in an office job at home and bring those clothes with you. Skirts should be to the knee though and no shorter.
Men should wear suit style trousers/pants, plain shirt, tie, dark coloured socks and smart black leather shoes.
Women should wear a shirt/blouse, knee length skirt and shoes (no sandals, flip flops or trainers) As it's a Buddhist country you should always cover your shoulders and refrain from wearing low cut tops.
For a more precise and regulated dress code please refer to your contract.
