Some travelers argue that, with the exception of obviously dangerous locations, travel in other countries poses no greater safety risks than being at home. In some countries, like China, you are probably safer because crimes against foreigners are virtually unheard of. Sometimes we feel unsafe only because our surroundings are unfamiliar; or because of language and cultural differences. Common sense, alertness, and good advance research and preparation go a long way toward reducing those fears. Before you travel to an unfamiliar destination do your research online and in travel books. There are lots of resources that will boost your confidence and reduce your risk.
Wear clothing that is appropriate for the culture and climate of the country. In many countries, particularly Asia, the Middle East and Africa, women do not wear revealing clothing in public and often cover their legs and arms as well. Check out what the locals are wearing and dress accordingly. You will be less conspicuous and lessen your risk of giving offense.
