Cute bathing suit and well made but I bought two I play suits, and this one though marked 12 months seems to be more like a 6 month size bathing suit... just fits snuggly on my big 3 month old, 17.5 lbs and 25.5. Will return it and keep my sea creatures pattern one as the waist had at least another inch, and I am layering swim diapers for a lesson and wanted one that was the size it should be.
