Those one-pieces showing too much skin? Want to go swimming but want to stay modest?

Now there's Wholesome Wear -- dresslike "swimsuits" for those who (I suppose) do not like to show skin at the beach for religious or other reasons. Their tagline is "Swimwear that highlights the face, not the body."

The unique swimwear feature two pieces -- a form-fitting inner layer and a dress-like outer layer -- both ending at about the knee. On one item, there is the option to buy an even more modest suit that terminates at mid-arm and mid-knee.

Wholesome Wear seem to be made for teenage girls as well as women. I'm curious as to what modest swimwear their brothers and fathers and husbands wear -- if they too have to wear two layers of longish clothing while at the beach or swimming in the water.
