That's really pretty. I'd probably just wear like a white (nude would be even better) underwear type cami. Something like this maybe. It's low enough that the top wouldn't show much, it would just provide coverage. I think this tank has a built in bra but anything similar would work because you could wear a regular bra with that top. Nice find! :)
Thanks that is what I was thinking. I definetly need to check out gap next time I need tanks since that one scoops kinda low. My other ones are pretty high
