They must have changed their swim nappies 7 years ago because they are hanging between their legs. You are the right size. There just seems to be more material between the legs, so when they get wet the swim diaper sags and my son has a big puddle of water between his legs. WE BOUGHT THE RIGHT SIZE again. We used the same product 7 years ago and they have been amazing. They didn't sag at all.
