Medium fits my 9 year old son. He's tall and slim for his age and the shirt suits him very well. His favorite are the thumb holes on the sleeves. He was intrigued by his father's similar shirt, especially the thumb holes. I found it difficult to find shirts with thumb holes his size and under his shirt. He is very happy with this shirt!
