This runs small. I made a size 98 with 104 length. My ds usually wears a straight 98, but its going to be a few weeks before he wears this shirt and I wanted a little growing room.

The shirt was the right length, no growing room that I was trying to add. The sleeves were an inch too short. I have to redo them!

The rest fit fine, it was just the overall length and the length of the sleeves.
