I ordered this suit for my daughter this summer, and she loved it! It was flattering and very comfortable for her. We had one issue with a strap coming undone after the first wearing. I contacted Knix and was immediately sent a new suit. She wore the new one for the rest of the summer, and we had no issues. I have also ordered Knix Swim for myself and will do it again.
