Dress in Thailand
Outward appearances are important for Thai people. Here, the old saying “clothes make the man” holds true. Thais appreciate farangs who make an effort to maintain a professional and reserved appearance.
T-shirts and shorts are acceptable for going just about anywhere; however, shorts should be of a modest length, while sports clothes and tank tops are worn almost exclusively for sporting activities.
For office jobs in Thailand, expats will be expected to wear fairly formal office attire. Women should avoid wearing sleeveless blouses, and jeans are a definite no. Men are expected to wear dressy pants and shirts with a collar; ties are not mandatory, but recommended when attending formal gatherings.
In beach towns – such as Phuket, Hua Hin and Krabi – Thais are more accustomed to foreigners wearing bikinis and swimming attire at the beach. However, whenever going for lunch or a stroll around town, people make sure to cover up and wear a shirt and shorts.
