The tag says size 80, but my child has a large head, so by the time they could wear size 80, it was too tight and they couldn't wear it. In my opinion, it's more like a size 70. I received it as a hand-me-down and was looking forward to using it because of the cute marine style, but my child couldn't wear it for the reason mentioned above. How about using it as a spare outfit or change of clothes for daycare?
