Very cute suit and nicely made, but the back is pretty high cut for a toddler. My daughter is 19months, but pretty tall, so she has to wear 3T, but the back of the suit exposes a good bit of swim diaper hanging out the sides. If she didn't have a diaper on, you'd see about the same as a standard adult bikini with a bit of "side cheek" showing. Needs more "coverage" in the back to be appropriate.
