How do you feel about 2 piece bathing suits for very young girls?

It's certainly not that important one way or the other but 3 of my closest friends and I have debated on this issue. I don't see anything wrong with it at all. I have an 8 month old, and my friends who oppose it have daughters ranging from 18 months -7 years old. Their biggest problem with it is that it is too tempting for dirty child molesters. I feel that in a public place a close eye should be kept on all children regardless of their even if they are wearing a snowsuit for God sakes. Is a one peice bathing suit less enticing for these dirty molesters? Am I just a bad mother for feeling that it's okay for small children to wear bikinis? I don't know why but this teeny tiny issue bothers me, what's your opinion?
