A3 Performance Female X-Back Solid Poly One Piece Swimsuit

My duaghter swims 8 times a week, and needs a long lasting swimwear. She has Arena, Waterpro, Mizuno, Asics, and A3. We bought it this April, and this was the newest and most expensive. She liked it a lot. She felt it comfortable, and the size was just right. After 5 months of use of twice a week, this one started worn out, while others are still fine. It was a bit of disappointment.
