Please read the description. If you have no questions, you can purchase the item immediately. These are matching swimsuits for parents and children. I bought them because I liked them, but neither the parent nor the child wore them, and they outgrew them, so I am selling them. The kids' swimsuit has an elastic waistband. For the kids' set, I will also include a Breeze shirt, which I bought as a rash guard. Inseam: Adult approx. 20cm, Child approx. 19cm Please note that these are amateur measurements, so there may be slight variations. Although they are unused, please understand that they have been stored at home before purchasing.
