After reading other reviews I ordered 8/10 for my almost 5 year old. I'm glad I'm this size because it's almost the right size. A size smaller would probably not fit at all. The sleeves are still a little tight, but that's ok. If you order it big enough to make up for the odd size, it's actually a pretty good swimsuit.
