Don't rely on the size grid. Yes, and it was said that my son would become a medium. My son has never worn a medium but I went with him anyway. He was too big. Polo itself looks good but thin. I had to exchange for a small one but haven't received it yet so I can't tell if the small one will fit or not. Let's see. For reference, my son is 8 years old on average. He is thin and usually wears a small old dark blue tag at all times.
