If you travel into developing countries and male-dominated societies, make every effort to dress modestly. In some places, customs based on religious and moral beliefs strongly influence the way the women dress. For you to blatantly break these rules would be considered irreverent and might put you in jeopardy. Why not adapt your clothing to fit the customs of the host country? It becomes an interesting and educational challenge.
Tip / Info: When visiting a religious site, a woman should always dress conservatively. A woman traveller should carry a scarf in case she needs to cover her head.
Outside North America, a one-piece swimsuit is always a safer choice than a bikini. In some countries, local women might swim entirely clothed, in accordance with their religious beliefs.
