I'm not sure if I should pack everything I need, or pack light and leave some room in my bag for clothes I can buy there. Is it still really traditional - do I need to be very covered up for day-to-day life?
Pack light! Chiangmai Mai is very used to travelers and some might even say it's touristy now, so that all points to wearing the same clothes as you would on any travels, though do bring a long sleeve shirt or light jacket/cardigan for visiting any temples. And yes,what you think you'll need, there's plenty a market to buy whatever on the cheap. about 6 years ago
