It's a good site, but not everything is going to be viewed as modest by conservatives--including me.
I don't think swimsuits are modest, personally, even if they are "full coverage." My girls and I wear swim trunks (board shorts) to the knees and rash guards. (Usually with a swimsuit underneath because of the tight fit and light weight material.)
For modest, practical, lightweight and protective (from the sun--not sharks) swimwear, try something like this:

or

We have fair skin anyway, so going bare in the sun would be pretty stupid--we'd all be fried. Jeffrey's poor back and shoulders blistered one time because I let him go without a shirt to swim--and he had multiple applications of sunscreen. (supposedly waterproof, but apparently not)
If I'm just with my girlfriends or Jeff and the kids, I might go a little lighter on the clothes, but at a beach or the lake with a mixed crowd? I think that calls for modest clothing. JMO!!!
