Is there harm in letting my daughters play around the house in bathing suits?

My daughters are 5 and 7. They seem to be obsessed with playing in their bathing suits. My husband thinks it is bad and thinks it sends the wrong message for us to let them do it. He thinks when they are older they will want to do this and will send the wrong message to others. I told him that they will want to when they are older. What is so wrong with that? I wear bathing suits. He said that women who get d are usually dressing in revealing clothing. He also said young girls who dress in skimpy clothing have promiscuous ways or have the appearance of trashiness. I am all for my daughters growing up to be strong, respectful, modest women, and I do not dress inappropriately. I feel that they are just little girls and they are exploring their bodies and their uality. If he keeps on getting on to them about it, then they will sense that there is something wrong and sinful about their bodies. I do not want to harm their self-esteem nor do I want to raise floozies. What should I do?
