I ordered a size 4/5 (which was marked small on the jacket) for my 41.5 inch son who will be 5 in a few months. Everything about the jacket was perfect except that the sleeves were two inches longer. I'm switching to a different one in the hope that this is a one-off bug. I will update when the exchange arrives. Update - ordered another one and still had the same issue :( Just to be clear my son's arms are not disproportionate to the rest of his body.
