This is a great suit for a beginner swimmer. I bought this as a gift for a friends daughter and when she tried it on she said "this is my new favorite suit!" She hadn't even swam in it yet. I bought a size 26 which is a kids size 10.
This is one of 2 suits I purchased for my 9 year old for diving. I ordered the same size a 10/26, my child weights all of 65 lbs, so she isn't terribly large for a 9 year old. As with the other we bought it runs really small in the sizing. She won't get much time in it before she outgrows it. She does love it however and feels quite comfortable wearing it. I wish I had know how small they really were, I will for sure have to order some others within a few months.
