I'm kinda feeling the same way. I wouldn't expect a swim suit to last more than one season anyway.
My daughter has 3 Speedo bathing suits that have lasted her 2 years already and are still in good condition. She won't be wearing them anymore as they are oo small now so we bought her 2 from LL Bean. My youngest one has had several bathing suits from Target/Walmart and they also have lasted more than one season so much so they were passed onto friends who need them.
