Well, we have to agree that the "wholesome" swimwear is for those who have issues (be they religious, sexual or confidence related) with showing a lot of skin.
For example, a lot of muslim women like to swim too you know. And many of them do not wear the burqa, but at the same time are not happy about bikinis. In fact, the same thing goes for some Christan and Jewish "fundamentalists".
Having said all that, I kind of posted this tongue-in-cheek. As is often the case, an interesting discussion was born out of a facetious remark.
