OP here. As I said before, I have small breasts and don't require support.
Here is my update:
I have worn the black rash guard without anything under it in the water. When its dry, its very comfortable for me. When I just come up from being submerged, the fabric clings in a way that is actually more revealing than I'm totally comfortable with. But it just takes a moment or 2 before the cling subsides and all seems normal again.
The thing about the cling that feels too exposed is the area between my breasts - when the fabric goes back to spanning straight across from nipple to nipple, then that seems fine to me. (and I fully support others who choose to be more or less conservative in how they cover their bodies)
For a long day at the pool, its still more comfortable than wearing a bikini top underneath. And easier than applying sunscreen. So I'll probably keep doing it.
