My son is slim, slightly above average height, 10 years old. He doesn't have clothes larger than 10-12 sizes, but based on reviews I ordered 14-16 sizes larger. They're a little baggy on him, which I can live with, but the sleeves are still a bit short, which is an issue. They only seem to be made for small or slightly chubby children.
