Two things
Previously, someone said you needed to dress up - don't wear shorts and t-shirts. I respectfully disagree with that. During the day plenty people wear shorts. Maybe if you are going out for supper or out at night, you might want to wear something a bit nicer.
Most people recognize you are a foreigner/tourist and are too polite to stare.
Additionally, I always carry a ziploc bag of flushable baby wipes when I am there. They come in handy in the bathroom, disinfecting my hands or wiping my face. It can be a shock to use the bathroom facilities only to find there isn't any toilet paper!
