On some beaches in France, Sweden, Australia, the U.S. and elsewhere, you can show up wearing skimpy swimsuits, topless or no clothing at all. However, when you want to sun yourself on other beaches, you must obey the local laws or you get in trouble.

For example, tourists are being warned to cover up on certain public beaches in the United Arab Emirates (UAE) or face a fine for showing too much skin. Authorities in Ras al-Khaimah emirate, have signs on public beaches warning of penalties for certain swimwear. Forbidden are two-piece bikinis and Speedo-style swim trunks for men.

The beaches are located 60 miles northeast of Dubai. Emirate officials enforce the rules because religious laws and local standards declare nudity and skimpy swimwear offensive to Dubai residents. So, wherever your travels allow to bathe and sun, be sure you know the local rules so you won’t expose too much of yourself (and your bank account).
