I found this interesting tidbit of info from the guys at Escapeblog. The Maldives is a Muslim Country. There are certain things that are not acceptable there like for example topless and/or naked sun bathing, that is even if you are in a resort. Other tips include
not wearing clothes that cover your knees and shoulders if entering a Mosque, not bringing in alcohol because it will be confiscated by immigration, and finally leaving you porn at home as it is illegal in the country.
