This swimsuit looks nice, it's well made, and the fabric is soft.  So why three starts?
First, the same strap is used to go around the neck and to tie the top on the back, and there is no way to regulate how much of it you want on the neck.  When you put it on, it fits perfectly, but then you go to the beach, move, swim and end up with a top that is barely covering what it should cover because it slipped up and became too loose around the chest.  I will probably have to sew the strap in several places, which will ruin the look, but at least will make the swimsuit wearable.
Second, the straps on the bottom are too long.  What are they for?  To make a bow?
