Swim diapers would be nice. You can also swim in your diaper. It will be super big after swimming but I’ve done it before and it feels amazingly little hahaha. I’ve always wanted to try wearing SwimMates in the pool but the only pool I have available is my parents pool and I don’t have the freedom to wear my diapers while swimming at their house anymore since I moved out and also my dad never put a privacy fence around the backyard so I always was super nervous swimming in my diapers. Always had to jump in with my bathing suit on and take it off once in the pool.
