Shorts and polo/t-shirt are OK to walk around to help you cope with the heat. There are however lots of must-see temples in Bangkok and the historic park in Ayutthaya consists of ruins of palaces and temples.
Thai Buddhist temples (Wats) are open to everyone. There are, however, several rules that you must observe.
Modest clothing is required, which means for ladies: a skirt or dress that covers the knees and a top with sleeves that covers the shoulders and is not transparent. For men, modest clothing means long pants and a shirt that covers the shoulders. Shorts will not do!
This "dress code" is also applies to the Grand Palace, Vimanmek Mansion and other royal sites in Thailand.
