I ordered two sizes: 15.5 and 16.5. I'm 16.5 but I'm skinny and most shirts this size are a lot roomier so I ordered a size down as I hate shirts that are baggy. He was a much better fit. The sleeves were a bit short but ok. I might try ordering with slightly longer sleeves than expected and a smaller collar size if you are skinny. They have a comfort collar that stretches so it's actually still very comfortable. I really recommend ordering several sizes and then returning the ones that don't fit. Returns are very easy to process and free.
