Super cute top! I removed a star because of the bottoms. For the size of baby theyll need a water diaper but the bottoms are so skimpy they are only 1 wide on the sides and very small length and would never fit over a water diaper. If you even got it on the entire water diaper would show under. I use a reusable washable white iplay water diaper and no bottoms and it looked cute anyway. Keep in mind rash guards are very tight especially the neck hole so get a size up if you want it a little loose. Its not like babies are on the swim team and need to swim under water quickly.
