Why do girls wear thongs?

I understand there are a variety of reasons. But it seems like most woman I have met seem to complain about wearing them, how they are uncomfortable, expensive, and so on. Yet they seem to have more pairs of thongs than other types of underwear. Why complain about it but still wear them? And yes I understand some woman will reply that they like them. Merely talking from previous experience.
