I must admit that I tend to always put plenty of research into a new destination, and that is not only research about sights to see and things to do, but just as much about local lifestyle, traditions, culture, and general day-to-day habits of the locals.
Luckily, I have never dressed as a tourist in those typical outfits of a backpack, sensible pants, all-weather jackets, ugly (if comfortable) sneakers, or sandals and socks, which make you stand out from a mile off. Instead, I dress as I would at home, as if I lived in the place and I’m just heading out for coffee, and this has often paid me back in that people approach me for directions, thinking I am a local.
