I thought this shirt ran pretty true to size. I made an 80 for my ds who is exactly 80cm, and it fits well with room to grow even. I love all the details on this shirt, and will probably be making more. It's a great button up shirt that's just a little different. I sewed the pocket pleats in the opposite direction because I liked them better that way. For the collar I used a bias strip to cover the raw edges rather than follow the pattern directions.
