If you are coming as a tourist, the above advice holds good. If you were coming to live here, you would want to err on the side of being dressed in a reserved fashion to start with until you have found your feet, maybe more reserved than you are accustomed to (despite how the local girls dress). Reputations once lost are hard to regain and many judge on appearances; not that they would ever tell you. But for a tourist who leaves after 1 or 2 weeks, maybe reputation isn't so crucial.
