Re: swim diapers and swimsuit questions?
Those swim bottoms are the bottoms. Swim dipes aren't made to absorb anything, but to contain messes. If you get a regular swimsuit, you can use a swim dipe under it - we used an unstuffed pocket as our swim dipes. Others have used snug-fitting covers as swim dipes. I suppose you could use the swim bottoms under a regular swimsuit, but that would get pretty bulky, and might look odd with both patterns showing.
