Is it appropriate to wear a thong when swimming at the seaside? Is it too exposed?

This question mainly tests your own psychological endurance. People in China are not making such a fuss as before. Many famous beaches in China can often see people wearing thongs sunbathing on the beach, even naked (in certain areas). Not to mention foreign countries, those celestial beaches, if you wear thongs, you will feel that you are too grand to get in. The main thing is to beat yourself and make others envy you.
