It can be tough to find a swimsuit that isn't revealing — and not everyone wants to flaunt it on vacation.

On their TLC show, 19 Kids & Counting, Michelle and Jim Bob Duggar are seen snorkeling on a marriage retreat in Puerto Rico. Instead of wearing typical bathing suits, they opted for suits from WholesomeWear.com, which describes itself as "a modest line of clothing for 'wherever.' Our WaterWear is the first to be introduced because the need for modesty in swimwear is the greatest and the supply is almost non-existent." Check out examples here.

Michelle talked to People about their choice to cover up. "In society, sometimes there's this idea that we cover up at certain times and then we go to the beach and wear our underclothes. Bathing suits are pretty and colorful but it's not our thinking that it is okay to be naked some places and not other places." She just wanted to find something she was comfortable in. "The eyes are the windows to the soul," Michelle added.  "And we are trying to keep our hearts pure, which is a struggle. Everyone has their idea of what is modest, but for our family, we try to avoid situations ... like the public beach or swimming pools that can make it a challenge to keep our minds pure."

Purity doesn't come too cheap. Just as an example, the "Culotte Swimmer" design on Wholesome Wear's site ranges from $55.20 for a Child's size to $75.20 for Ladies.
